Geometry and its Interfaces

Tamas Hausel's research interests include combinatorial, differential and algebraic geometry and topology. The main tool used is representation theory, connecting our investigations  to number theory and physics. 

The more specific focus is the study of the geometry, topology and arithmetic of several moduli spaces appearing in supersymmetric quantum field theories including moduli spaces of Yang-Mills instantons in four-dimensions, the moduli space of magnetic monopoles in three dimensions and the moduli space of Higgs bundles in two dimensions. The questions we are concerned with have motivations in mathematical physics, such as string theory and topological quantum field theory as well as in number theory, in particular in the realm of the Langlands program. 

The immediate question is to describe the topology of such spaces, starting with the structure of holes of various dimensions. Besides the traditional techniques of global analysis and Morse theory, we also employ arithmetic methods, which in turn will invariably lead to problems in representation theory of various objects in algebra. Examples include the representation theory of quivers, finite groups and algebras of Lie type and various Hecke algebras. 

What results is a colorful palette of subjects in mathematics and theoretical physics and our focus is on the interconnectedness of these fields inside mathematics.
