Özet

Abstract: The Kr-core of a complex valued sequence has been introduced in [5]. In this paper, we have determined a class of matrices such that Kr?core(Ax)?Kr?core(x) hold for all x?1?. Also; we have defined a new type of absolute equivalence, r - absolute equivalence, and characterized these type of matrices.
