Seminar on Continuous K-theory: Introduction and motivation to continuous K-theory
Speaker: Christopher Brav Abstract: This will be an introductory and organization talk for a joint reading seminar with Guozhen Wang, on continuous K-theory in the sense of Alexander Efimov. In brief, “continuous” K-theory is an extension of algebraic K-theory to a certain nice class of well-behaved large categories for which the classical construction of algebraic …

【算子代数讲座】A higher index for finite-volume locally symmetric spaces
Speaker: Hang Wang (ECNU) Abstract: Let G be a connected, real semisimple Lie group, and K a maximal compact subgroup. For a discrete subgroup Γ in G, we have the locally symmetric space X = Γ\G/K. Such spaces appear in many places in mathematics and include, for example, all hyperbolic manifolds. Our research was strongly …

SIMIS Seminar on Field Theory and String Theory: Mirror symmetry via Floer theoretic invariants with support
Speaker: Umut Varolgunes Abstract: I will outline an approach to mirror symmetry where the A-side is a symplectic CY manifold “symplectically cut” into certain small pieces and the B-side is a non-archimedean analytic space glued from Floer theoretic invariants of those pieces. This suggests a clear path for conceptual explanations to homological mirror symmetry and …
Diagonals in classifiable C*-algebras
Wilhelm Winter (Universität Münster) 14:00-15:00, July 31th, 2024 Shanghai Institute for Mathematics and Interdisciplinary Sciences Abstract: Cartan and diagonal subalgebras encode underlying dynamical structures of C*-algebras via their associated groupoids. The existence of Cartan subalgebras in separable, simple, nuclear C*-algebras is closely related to the UCT problem, but even for well-known classifiable ambient C*-algebras, we have …
A geometric Elliott invariant
Hang Wang (East China Normal University) 11:00-12:00，July 31th，2024 Shanghai Institute for Mathematics and Interdisciplinary Sciences Abstract: We develop a geometric approach to the Elliott invariant for a free, minimal action of $\mathbb{Z}^d$ on a compact space with finite covering dimension. This approach relies on topological and index-theoretic data from the mapping torus associated with the …
