Non-Kahler Calabi-Yau geometry and pluriclosed flow

October 4, 2022

Zoom talk

Hermitian, pluriclosed metrics with vanishing Bismut-Ricci form give a natural extension of Calabi-Yau metrics to the setting of complex, non-Kahler manifolds, and arise independently in mathematical physics. We reinterpret this condition in terms of the Hermitian-Einstein ... Read more

Compactness within the space of complete, constant Q-curvature metrics on the sphere with isolated singularities

October 25, 2022

PIMS Lounge

This talk addresses the moduli space of complete, conformally flat metrics metrics on a sphere with $k$ punctures having constant positive $Q$-curvature and positive scalar curvature. Previous work has shown that such metrics admit an asymptotic expansion near each puncture, ... Read more

The asymptotic geometry of the Hitchin moduli space

November 15, 2022

Zoom talk

Hitchin's equations are a system of gauge theoretic equations on a Riemann surface that are of interest in many areas including representation theory, Teichmuller theory, and the geometric Langlands correspondence. The Hitchin moduli space carries a natural hyperkahler metric ... Read more
