Global Analysis and PDEs
Global Analysis and the theory of partial differential equations are classical fields of mathematics that have a wide range of applications within mathematics, for instance in number theory, group theory, geometry and topology, but also have important applications outside of mathematics to physics, engineering and chemistry.
The Global Analysis and PDEs research group is rooted in pure mathematics and focuses on geometric and topological aspects of analysis. The interests of the group include spectral and scattering theory on manifolds, regularity and existence of global solutions to pseudo-differential equations and boundary value problems, topological questions related to generalizations of the Atiyah-Singer index theorem, applications of theory of PDE to approximation theory, as well as other topics.
Academic staff within the group are:
