Özet

In [11] and [7], the concepts of or-core and statistical core of a bounded number sequence x have been introduced and also some inequalities which are analogues of Knopp's core theorem have been proved. In this paper, we characterize the matrices of the class (S boolean AND m, V-sigma)(reg) and determine necessary and sufficient conditions for a matrix A to satisfy sigma-core(Ax) subset of or equal to st-core(x) for all x is an element of m.
