Journal of Operator Theory, Vol. 63, No. 1 (Winter 2010), pp. 3-46 (44 pages) We investigate the codimension of commutator spaces [I,B(H)] of operator ideals on a separable Hilbert space, i.e., "How ...

The simple definition of a mean is that of a numeric quantity which represents the center of a collection of numbers. Here the trick lies in defining the exact type of numeric collection, as beyond ...

Generalized quasi-arithmetic means extend the classical concept of averaging by employing continuous, strictly monotonic functions to transform and then re-transform data. Originally introduced to ...

Abstract. In this paper we study inequalities among quasi-arithmetic means for a continuous field of self-adjoint operators, a field of positive linear mappings and continuous strictly monotone ...
