In the present paper, we introduce a new type core, K-q-core, of a complex valued sequence and also determine the required conditions for a matrix B for which K-q-core (Bx) subset of K-core (x), K(q)core (Bx) subset of st(A)-core (x) and K-q-core (Bx) subset of K-q-core (x) hold for all x is an element of l(infinity).eninfo:eu-repo/semantics/closedAccessMatrix transformationscore of a sequencestatistical convergenceArticle24135392-s2.0-79551556834Q3WOS:000421116000005N/A
