Keywords:
linear operators in spaces with indefinite scalar product; semigroups of linear bounded operators; inverse problems.
Subject:
Properties of Jordan representations of dissipative operators acting on finite dimensional indefinite space and the structure of such operators have been investigated (with T. Ya. Azizov). Necessary and sufficient conditions of solvability on one step of an inverse eigenvalue problem for symmetri tridiagonal quadratic pencil have been obtianed. Criteria for the similarity of a maximal dissipative operator on a Pontryagin spase to a maxima Hilbert space dissipative operator (joint with T. Ya. Azizov, A. Dijksma, P. Jonas).
