On reflexive subobject lattices and reflexive endomorphism algebras
In this paper we study the reflexive subobject lattices and reflexive endomorphism algebras in a concrete category. For the category Set of sets and mappings, a complete characterization for both reflexive subobject lattices and reflexive endomorphism algebras is obtained. Some partial results are also proved for the category of abelian groups.
On reflexivity and hyperreflexivity of some spaces of intertwining operators
Let be weak contractions (in the sense of Sz.-Nagy and Foiaş), the minimal functions of their parts and let be the greatest common inner divisor of . It is proved that the space of all operators intertwining is reflexive if and only if the model operator is reflexive. Here means the compression of the unilateral shift onto the space . In particular, in finite-dimensional spaces the space is reflexive if and only if all roots of the greatest common divisor of minimal polynomials...

On regularities and Fredholm theory
We investigate the relationship between the regularities and the Fredholm theory in a Banach algebra.

On reiteration and the behaviour of weak compactness under certain interpolation methods.
This article deals with K- and J-spaces defined by means of polygons. First we establish some reiteration formulae involving the real method, and then we study the behaviour of weakly compact operators. We also show optimality of the weak compactness results.
