András Vasy (born 1969) is a Hungarian–American mathematician working in the areas of

partial differential equations In mathematics, a partial differential equation (PDE) is an equation which involves a multivariable function and one or more of its partial derivatives. The function is often thought of as an "unknown" that solves the equation, similar to how ...

microlocal analysis In mathematical analysis, microlocal analysis comprises techniques developed from the 1950s onwards based on Fourier transforms related to the study of variable-coefficients-linear and nonlinear partial differential equations. This includes genera ...

scattering theory In physics, scattering is a wide range of physical processes where moving particles or radiation of some form, such as light or sound, are forced to deviate from a straight trajectory by localized non-uniformities (including particles and radiat ...

Awards and honors

Vasy was an Alfred P. Sloan Research Fellow from 2002 to 2004, and a Clay Research Fellow from 2004 to 2006. He was elected a Fellow of the American Mathematical Society in 2012. He was an invited speaker at the International Congress of Mathematicians in Seoul in 2014. In 2017, he was awarded the

Research

The unifying feature of Vasy's work is the application of tools from microlocal analysis to problems in hyperbolic partial differential or pseudo-differential equations. He analyzed the propagation of singularities for solutions of wave equations on manifolds with corners or more complicated boundary structures, partially in joint work with
