Subprojective Banach spaces
Timur Oikhberg, Eugeniu Spinu
A Banach space is called subprojective if any of its infinite dimensional subspaces contains a further infinite dimensional subspace complemented in . This paper is devo…
Ideals of operators on -algebras and their preduals
T. Oikhberg, E. Spinu
In this paper we consider we study various classical operator ideals (for instance, the ideals of strictly (co)singular, weakly compact, Dunford-Pettis operators) either on -a…
Operator ideals on non-commutative function spaces
T. Oikhberg, E. Spinu
Suppose and are Banach spaces, and , are operator ideals (for instance, the ideals of strictly singular, weakly compact, or compact operators…
Domination of operators in the non-commutative setting
Timur Oikhberg, Eugeniu Spinu
We consider majorization problems in the non-commutative setting. More specifically, suppose and are ordered normed spaces (not necessarily lattices), and $0 \leq T \leq S…
Norm closed operator ideals in Lorentz sequence spaces
Anna Kaminska, Alexey I. Popov, Eugeniu Spinu +2
In this paper, we study the structure of closed algebraic ideals in the algebra of operators acting on a Lorentz sequence space.
