Krein space unitary dilations of Hilbert space holomorphic semigroups

Stefania Marcantognini

The infinitesimal generator $A$ of a strongly continuous semigroup on a Hilbert space is assumed to satisfy that $B_{β} := A - β$ is a sectorial operator of angle less than $\frac{π}{2}$ f…

Schur complements of selfadjoint Krein space operators

Maximiliano Contino, Alejandra Maestripieri, Stefania Marcantognini

Given a bounded selfadjoint operator W on a Krein space H and a closed subspace S of H, the Schur complement of W to S is defined under the hypothesis of weak complementability. A…
