C 0-groups andC 0-semigroups of linear operators on hereditarily indecomposable Banach spaces

Archiv der Mathematik, 1996
The authors show that in a hereditarily indecomposable Banach space, briefly H.I. space, generators of \(C_0\)-groups and \(C_0\)-semigroups exhibit various very special properties. The generator A of a \(C_0\)-group on such a space is always bounded, and if the group has polynomial growth of order k there is a unique point \(\lambda_A\) in the ...

One-parameter groups of orthogonality preservers on C$$^*$$-algebras

Banach Journal of Mathematical Analysis, 2020
We establish a more precise description of those surjective or bijective continuous linear operators preserving orthogonality between C$^*$-algebras.

Similarity Problems, Følner Sets and Isometric Representations of Amenable Semigroups

Mediterranean Journal of Mathematics, 2018
We revisit Sz.-Nagy’s criteria for similarity of Hilbert space bounded linear operators to isometries or unitaries and present new ones. We also discuss counterparts of the Dixmier–Day theorem concerning bounded representations of amenable groups and ...
