Analysis

We study a wide range of problems in classical and modern analysis. Our research interest includes geometric analysis, spectral theory of differential operators, real harmonic analysis and non-smooth partial differential equations, perturbation theory of differential operators, non-linear partial differential equations, special functions and their applications in physics, operator theory and operator algebras, non-commutative geometry, abstract harmonic analysis, non-standard analysis and its applications, topological K-theory and index theory, ergodic theory and application in geometry and number theory, representations of Lie groups, and analysis on symmetric and locally symmetric spaces.
