Research summary
AI-generated

Donu Arapura works in algebraic geometry, a branch of mathematics studying shapes defined by polynomial equations, with a focus on Hodge theory (tools that use complex analysis to understand the structure of algebraic varieties) and related topics like perverse sheaves and moduli spaces (spaces that parametrize families of geometric objects such as curves or vector bundles). Much of the recent work concerns Euler characteristics, singularities, and cohomological invariants of complex algebraic varieties and their fundamental groups. This research is highly theoretical and connects to number theory and complex geometry.
