Research Activity

• Ergodic theory with emphasis on connections with number theory, functional equations,and complex function theory.
• Banach spaces and Banach algebras, especially those consisting of continuous functions.
• Infinite matrices as operators on classical sequence spaces.
• Non-linear functional analysis with applications to differential equations.
• Approximation theory, Fourier analysis, wavelets, and differential equations, with emphasis on applications in inverse problems and tomography.
• Analysis and differential equations on groups and fractals.
• Infinite-Dimensional Analysis
