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.trinfo:eu-repo/semantics/openAccessOn the $K_r$ -core of complex sequences and the absolute equivalence of summability matricesArticle9340941638333
