The set of fibrations over manifold X which are fibrewise bordant has a canonical ring structure with respect to which a vertical genus is determined by certain combinations of `vertical characteristic classes' taking values in the singular cohomology of X. Family index densities provide natural examples. It turns out that the structures involved are governed by a vertical Pontryagin-Thom spectrum and its associated generalised (co)homology. These themes and, in particular, how the orientation along the fibres is a crucial ingredient, will be the focus of this talk. https://mediaup.uni-potsdam.de/Play/10496 Tue, 10 Sep 2019 13:44:53 GMT https://mediaup.uni-potsdam.de/Play/10496 Claire Debord - Microlocal and Global Analysis, Interactions with Geometry Index theory through Lie groupoids. The aim of this lecture is to explain why Lie groupoids are very naturally linked to Atiyah-Singer index theory. After introducing Lie groupoids, and giving various examples, I will explain how these geometrical objects can be used: - to construct the pseudodifferential calculus, - to construct the index of pseudodifferential operators without using the pseudodifferential calculus, - to prove and generalize index theorems. This talk, inspired by ideas of A. Connes, will be based on joint works with JM. Lescure and with G. Skandalis. https://mediaup.uni-potsdam.de/Play/10495 Tue, 10 Sep 2019 13:41:01 GMT https://mediaup.uni-potsdam.de/Play/10495 Paolo Piazza - Microlocal and Global Analysis, Interactions with Geometry K-theory classes of Dirac-type operators on stratifed pseudo manifolds. Let G be a discrete group and let X be a G-Galois covering with quotient X=G, a smooth compact manifold. Given a G-equivariant operator of Dirac-type one can define a K-homology class in the equivariant K- homology of X and an index class in the K-theory of the reduced C*-algebra of G. If the operator is L2-invertible, then we also have a rho class. In this talk, extending previous joint results with Pierre Albin and with Vito Zenobi, I will report on recent work with Pierre Albin and Jesse Gell-Redman addressing the existence of these classes for a general Dirac-type operator on (the regular part of) a stratifed pseudomanifold. https://mediaup.uni-potsdam.de/Play/10494 Tue, 10 Sep 2019 13:34:08 GMT https://mediaup.uni-potsdam.de/Play/10494 Maxim Braverman - Microlocal and Global Analysis, Interactions with Geometry The index of a local boundary value problem for strongly Callias-type operators. We consider a complete Riemannian manifold M whose boundary is a disjoint union of nitely many complete connected Riemannian manifolds. We compute the index of a local boundary value problem for a strongly Callias-type operator on M. Our result extends an index theorem of D. Freed to non-compact manifolds, thus providing a new insight on the Horava-Witten anomaly. https://mediaup.uni-potsdam.de/Play/10493 Tue, 10 Sep 2019 13:31:51 GMT https://mediaup.uni-potsdam.de/Play/10493 Nils Dencker - Microlocal and Global Analysis, Interactions with Geometry The Solvability of Differential Equations. Since Hans Lewy sixty years ago presented his famous counterexample, it has been known that nonsymmetric linear partial di erential equations are generically not solvable. For di erential operators with simple characteristics, solvability is equivalent to the Nirenberg-Treves condition ( ). This condition involves the sign changes of the symbol of the nonsymmetric part of the highest order terms. Condition ( ) also has consequences for the stability of the spectrum and for nonlinear di erential equations. In this talk, we shall consider di erential operators that have double characteristics. Examples are weakly hyperbolic operators and parabolic operators. Then one can de ne conditions corresponding to ( ) on the lower order terms at the double characteristics. We shall show that these conditions are necessary for solvability in several cases. A particularly interesting case are the weakly hyperbolic operators. https://mediaup.uni-potsdam.de/Play/10492 Tue, 10 Sep 2019 13:29:13 GMT https://mediaup.uni-potsdam.de/Play/10492 Andr&#225;s Vasy - Microlocal and Global Analysis, Interactions with Geometry Boundary rigidity and the local inverse problem for the geodesic X-ray transform on tensors. In this talk, based on joint work with Plamen Stefanov and Gunther Uhlmann, I discuss the boundary rigidity problem on manifolds with boundary (for instance, a domain in Euclidean space with a perturbed metric), i.e. determining a Riemannian metric from the restriction of its distance function to the boundary. This corresponds to travel time tomography, i.e. nding the Riemannian metric from the time it takes for solutions of the corresponding wave equation to travel between boundary points. A version of this relates to nding the speed of seismic waves inside the Earth from travel time data, which in turn permits a study of the structure of the inside of the Earth. This non-linear problem in turn builds on the geodesic X-ray transform on such a Riemannian manifold with boundary. The geodesic X-ray transform on functions associates to a function its integral along geodesic curves, so https://mediaup.uni-potsdam.de/Play/10491 Tue, 10 Sep 2019 13:26:25 GMT https://mediaup.uni-potsdam.de/Play/10491 Karen Yagdjian - Microlocal and Global Analysis, Interactions with Geometry A novel integral transform approach to solving partial differential equations in the curved space-times. In the talk we will present the integral transform that allows us to construct solutions of the hyperbolic partial di erential equations with variable coecients via solutions of a simpler equation. The transform was suggested by the author in the case when the last equation was a wave equation. Then it was used to investigate several well-known equations such as generalized Tricomi equation, the Klein{Gordon equation in the de Sitter, Einstein-de Sitter, and FLRW space-times. More precisely, this integral transform is aimed to generate representation formulas for the solutions to the equation https://mediaup.uni-potsdam.de/Play/10490 Tue, 10 Sep 2019 13:21:15 GMT https://mediaup.uni-potsdam.de/Play/10490 Bernard Helffer - Microlocal and Global Analysis, Interactions with Geometry On Courant's nodal domain property for linear combinations of eigenfunctions (after P. Bérard and B. Helffer). We revisit Courant's nodal domain property for linear combinations of eigenfunctions. This property was proven by Sturm (1836) in the case of dimension 1. Although stated as true for the Dirichlet Laplacian in dimension > 1 in a footnote of the celebrated book of Courant-Hilbert (and wrongly attributed to H. Herrmann, a PhD student of R. Courant), it appears to be wrong in dimension > 1. This was rst observed by V. Arnold in the seventies. In this talk, we present simple and explicit counterexamples to this so-called "Herrmann's statement" for domains in Rd, S2, or T2. We also discuss the existence of a counterexample in a C1, convex domain in R2 in relation with the analysis of the number of domains delimited by the level sets of a second eigenfunction for the Neumann problem. We nally discuss the question to have positive statements.

In the talk we introduce a quaternionic analogue of the Heisenberg group and explain the relation between this group and the quaternionic analogous of the Siegel upper half space. We discuss regular functions, that are counterpart of complex holomorphic functions for quaternionic setting. The Hardy space is the space of regular functions in the Siegel upper half space with L2 boundary values. We construct the Cauchy-Szego kernel for the Cauchy-Szego projection integral operator from the space of L2-integrable functions de ned on the boundary of the quaternionic Siegel upper half space to the space of boundary values of the quaternionic regular functions of the Hardy space over the quaternionic Siegel upper half space. We also present the fundamental solution for a hypoelliptic operator related to the boundary of the Siegel upper half space.

With a view toward sub-Riemannian geometry, we introduce and study H-type foliations. These structures are natural generalizations of K-contact geometries which encompass as special cases K-contact manifolds, twistor spaces, 3K-contact manifolds and H-type groups. Under an horizontal Ricci curvature lower bound, we prove on those structures sub-Riemannian diameter upper bounds and rst eigenvalue estimates for the sub-Laplacian. Then, using a result by Moroianu-Semmelmann, we classify the H-type foliations that carry a parallel horizontal Cli ord structure. Finally, we prove an horizontal Einstein property and compute the horizontal Ricci curvature of those spaces in codimension more than 2.

Consider a graphene tube in the shape of a right circular open-ended cylinder whose height and radius are both much greater than the distance between neighboring carbon atoms. A magnetic eld everywhere vanishing on the tube surface (or at least tangent to it) is adiabatically switched on, causing the eigenvalues of the tightbinding Hamiltonian describing the electron -states in graphene in the nearest neighbor approximation to move in the process. If the magnetic ux through the tube in the nal con guration has an integer number of ux quanta, then the nal Hamiltonian is unitarily equivalent to the initial one, and hence the electron energy spectrum returns to its original position. Moreover, the lattice function space on which the tight-binding Hamiltonian acts being nite-dimensional, the spectral ow of the Hamiltonian, de ned as the net number of eigenvalues (counted with multiplicities) that pass through https://mediaup.uni-potsdam.de/Play/10486 Tue, 10 Sep 2019 13:09:39 GMT https://mediaup.uni-potsdam.de/Play/10486 Juan Gil - Microlocal and Global Analysis, Interactions with Geometry Encomium Professor Bert-Wolfgang Schulze https://mediaup.uni-potsdam.de/Play/10485 Tue, 10 Sep 2019 13:06:03 GMT https://mediaup.uni-potsdam.de/Play/10485 Jochen Br&#252;ning - Microlocal and Global Analysis, Interactions with Geometry Some remarks on equivariant spectral theory. We consider a compact G-manifold, M, a G-vector bundle, E, over M, and a G-equivariant self-adjoint elliptic operator, A, of order one acting on the smooth sections of E. We restrict the operator to the -isotypical subspace of sections and show that its -function is meromorphic in the whole complex plane, but possibly with poles of higher order; 0 is not a pole, though. This result is derived from the equivariant heat expansion, that in this case contains nonlocal coecient and logarithmic terms. This approach leads to a proof of the equivariant APS-Theorem. This is joint work with Ken Richardson. https://mediaup.uni-potsdam.de/Play/10484 Tue, 10 Sep 2019 13:01:53 GMT https://mediaup.uni-potsdam.de/Play/10484 Alexander Strohmaier - Microlocal and Global Analysis, Interactions with Geometry A trace formula for stationary spacetimes.

L2-invariants are de ned in terms of the universal covering of a compact manifold as counterparts of classical invariants such as Betti numbers, the index of elliptic operators, or the analytic torsion. They have important applications in topology and geometry. In particular, they are related to the study of the asymptotic behavior of Betti numbers, analytic torsion and other spectral invariants for sequences of nite coverings converging in the Benjamini-Schramm sense to the universal covering. In this talk I will consider this problem for locally symmetric spaces. This is closely related to the limit multiplicity problems of DeGeorge-Wallach, Delorme and others.

For a strongly elliptic pseudodi erential operator P of order 2a (generally noninteger) | for example the fractional Laplacian (􀀀)a, 0 < a < 1 | there is a useful theory for boundary value problems on smooth subsets of Rn, when P satis es Hormander's a-transmission condition at the boundary. For the homogeneous Dirichlet problem (u supported in ), the solution space for data in Hs( ), s  0, is then the a-transmission space Ha(2a+s)( ) = (􀀀a) + e+Ha+s( ), where (t) + denotes an order-reducing pseudodi erential operator of plus-type. A similar result holds in Holder-Zygmund spaces.
