On isomorphisms of standard operator algebras
Lajos Molnar
The aim of this paper is to show that between standard operator algebras every bijective map with a certain multiplicativity property related to Jordan triple isomorphisms of assoc…
Local automorphisms of the unitary group and the general linear group on a Hilbert space
Lajos Molnar, Peter Semrl
We prove that every 2-local automorphism of the unitary group or the general linear group on a complex infinite-dimensional separable Hilbert space is an automorphism. Thus these t…
On some automorphisms of the set of effects on Hilbert space
Lajos Molnar
The set of all efects on a Hilbert space has an affine structure (it is a convex set) as well as a multiplicative structure (it can be equipped with the so-called Jordan triple pro…
*-semigroup endomorphisms of B(H)
Lajos Molnar
Let H be a complex infinite dimensional Hilbert space. We describe the form of all *-semigroup endomorphisms of B(H) which are uniformly continuous on every commutative C*-suba…
