Classical, Functional and Numerical Analysis

Fields of interest: Classical Analysis, Linear Algebra, Functional Analysis, Operator Theory with applications to Numerical Analysis.

Concrete topics include: localization of spectra of families of linear transformations, invariant subspaces of linear transformations and their perturbations, errors of solving linear equations in vector spaces, numerical summation of functions, and norms and numerical ranges in Banach algebras with or without identity.
