Title: Some sequence spaces and some special operators

Abstract:

In this presentation we will show some results related to the new class of sequence spaces, defined via Riordan numbers and prove their topological properties, and inclusion relations, obtain Schauder basis, and describe α β γ duals of them. We have given conditions under which there is matrix transformation between those new sequence spaces and the well-known classical sequence spaces. In the last part, we are given some results related to some special operator classes, such as approximable operators, nuclear operators, and ideal operators.
