Some linear preserver problems on B(H) concerning rank and corank
Lajos Molnar
As a continuation of the work on linear maps between operator algebras which preserve certain subsets of operators with finite rank, or corank, here we consider the problem inbetwe…

An algebraic approach to Wigner's unitary-antiunitary theorem
Lajos Molnar
We present an operator algebraic approach to Wigner's unitary-antiunitary theorem using some classical results from ring theory. To show how effective this approach is, we prove a…

On local automorphisms of group algebras of compact groups
Lajos Molnar, Borut Zalar
We show that with few exceptions every local isometric automorphism of the group algebra of a compact group is an isometric automorphism.
