The Gross-Hopkins duality

Ningchuan Zhang (UIUC Math)

Abstract: In this talk, we introduce the Gross-Hopkins duality in chromatic homotopy theory, which relates the the Spanier-Whitehead duality and the Brown-Comenetz duality in the $K(n)$-local category. We will mainly focus on the underlying algebraic geometry of the duality phenomena and work out some explicit examples at height 1.

A path approach to holonomy for singular foliations

Joel Villatoro (KU Leuven)

Abstract: This talk concerns a joint project with Alfonso Garmendia. The holonomy groupoid is a fundamental invariant of foliation theory. An important advance in the understanding of singular foliations when Androulidakis and Skandalis showed how to construct a topological groupoid that generalized the usual holonomy groupoid of a classical foliation. A drawback to their approach was that the construction of the groupoid itself was radically different to the traditional construction of the holonomy groupoid. In this talk, I will explain another way to construct the same object which is a more straightforward generalization of the classical construction.
