Similarities of subspace lattices in Banach spaces
Janko Bračič, Marko Kandić
A collineation of a subspace lattice $\fL$ in a complex Banach space $\eX$ is an invertible operator on $\eX$ with the property that the image $S\eM$ of a subspace $\eM$ belong…
Hyperinvariant subspaces for sets of polynomially compact operators
Janko Bračič, Marko Kandić
We prove the existence of a non-trivial hyperinvariant subspace for several sets of polynomially compact operators. The main results of the paper are: (i) a non-trivial norm closed…
Local commutants and ultrainvariant subspaces
Janko Bračič
For an operator on a complex Banach space and a closed subspace , the local commutant of at is the set of all operators on such that…
On Automatic Continuity of 3-Homomorphisms on Banach Algebras
Janko Bracic, Mohammad Sal Moslehian
A linear map between (Banach) algebras is called 3-homomorphism if for each . We investigate 3-hom…
