The main result of this paper gives a minimal set of sufficient conditions for a triangle T : A(k) -> A(k) for the sequence space A(k) defined as follows: A(k) := {{s(n)} : (n=1)Sigma(infinity)n(k-1)vertical bar a(n)vertical bar(k) < infinity, a(n) = s(n) - s(n-1)}.eninfo:eu-repo/semantics/closedAccessBounded OperatorTriangular MatricesA(K) SpacesWeighted Mean MethodsTriangles Which Are Bounded Operators on AkArticle322Q2Q1223231WOS:000265913500010
