Title: Harris-Venkatesh plus Stark Abstract: The class number formula describes the behavior of the Dedekind zeta function at s=0 and s=1. The Stark and Gross conjectures extend the class number formula, describing the behavior of Artin L-functions and p-adic L-functions at s=0 and s=1 in terms of units and class numbers. The Harris-Venkatesh conjecture describes […]

Title: Modelling crisp type theory Abstract: Crisp type theory is a modal type theory originating in work of Pfenning and Davies (2001) and developed by Shulman (2018) for investigations in homotopy type theory. It is conjectured to be modelled by some generalised kind of comma category. In this talk, I will follow Pfenning and Davies to […]

Analysis seminar: Christopher Kauffman (Münster)

Title: Stability of perturbed wave equations on Kerr black hole spacetimesAbstract: I will discuss a recent work with Gustav Holzegel, in which we prove integrated decay bounds for solutions of the geometric wave equation with small linear perturbations on Kerr black hole spacetimes.Our proof adapts the framework introduced by Dafermos, Rodnianski, and Shlapentokh-Rothman for the homogeneous wave […]
