On the ascent and the angle between the null space and the range of elementary operators
Janko Bračič, Bojan Kuzma, Hranislav Stanković
We study the angle between the null space and the range of elementary operators of length one or two acting on , the Banach algebra of all bounded linear…
Reflexive subspace lattices in Banach spaces
Janko Bračič
In this survey paper we present known results about reflexive subspace lattices. We show that every nest and every atomic Boolean subspace lattice in a complex Banach space is refl…
Collineations preserving the lattice of invariant subspaces of a linear transformation
Janko Bračič, Marko Kandić
Given a linear transformation on a finite-dimensional complex vector space $\eV$, in this paper we study the group $\Col(A)$ consisting of those invertible linear transformatio…
On the invertibility of elementary operators
Nadia Boudi, Janko Bračič
Let be a complex Banach space and be the algebra of all bounded linear operators on . For a given elementary operator of l…
