On relationships between two linear subspaces and two orthogonal projectors
Sum and intersection of linear subspaces in a vector space over a field are fundamental operations in linear algebra. The purpose of this survey paper is to give a comprehensive approach to the sums and intersections of two linear subspaces and their ...

C-symmetric operators and reflexivity
We study subspaces of all C -symmetric operators. Description of the preanihilator of all C -symmetric operators is given. It is shown that the subspace of all C -symmetric operators is transitive and 2-hyperreflexive. Mathematics subject classification (

On a class of shift-invariant subspaces of the Drury-Arveson space
In the Drury-Arveson space, we consider the subspace of functions whose Taylor coefficients are supported in a set Y⊂ ℕd with the property that ℕ\X + ej ⊂ ℕ\X for all j = 1, . . . , d.

Bishop's property (β), hypercyclicity and hyperinvariant subspaces
The question whether every operator on H has an hyperinvariant subspace is one of the most difficult problems in operator theory. The purpose of this paper is to make a beginning on the hyperinvariant subspace problems for another class of operators ...

On supercyclicity for abelian semigroups of matrices on ℝ^n
We give a complete characterization of supercylicity for abelian semigroups of matrices on Rn , n 1 . We solve the problem of determining the minimal number of matrices over R which form a supercyclic abelian semigroup on Rn . In particular, we show that

Inner multipliers and Rudin type invariant subspaces
Let $\mathcal{E}$ be a Hilbert space and $H^2_{\mathcal{E}}(\mathbb{D})$ be the $\mathcal{E}$-valued Hardy space over the unit disc $\mathbb{D}$ in $\mathbb{C}$.

Boundary behavior of functions in the de Branges--Rovnyak spaces
This paper deals with the boundary behavior of functions in the de Branges--Rovnyak spaces. First, we give a criterion for the existence of radial limits for the derivatives of functions in the de Branges--Rovnyak spaces.
