Yu Yuan: Special Lagrangian and quadratic Hessian equations
University of Washington
Location: Hill 525
Date & time: Thursday, 16 October 2025 at 2:00PM - 3:20PM
Abstract:
We survey some new and old, positive and negative results on a priori
estimate, regularity, rigidity, and constant rank results for special
Lagrangian and quadratic Hessian equations. These equations originate in
calibrated, convex, conformal, and complex geometries among other fields.
Unlike all other order Hessian equations such as the linear (Laplace) and top
order (Monge-Ampere) equations, the regularity/irregularity and a priori Hessian estimates
for these two equations have not been settled yet in five and higher dimensions.
