Interests

Representation Theory, Linear Algebra, Operator Theory of bounded operators. My iverstigations are focused on several themes. Among them are:

Representation of a matrix (or a bounded operator) by a linear combination (+1,"+"or "-" 1, integer, positive, real, complex coefficients) of idempotents or orthoprojections.

Representation of a matrix as a product of unitary matrices with a fixed spectrum.

Applications of a sum and a product of projections in Numerical Analysis, Knots Theory, Functional Analysis and so on.

An inverse eigenvalue problem: finding the possible spectrum of C=A+B for given spectra of A and B.

Complete sets of unitary invariants of a matrix. Invariant Theory and Representations.
