KÖTHETOEPLITZ DUALS OF SOME NEW SEQUENCE SPACES AND THEIR MATRIX MAPSZ.U. Ahmad and MursaleenDepartment of Mathematics, Aligarh Muslim University, Aligarh 202001, IndiaAbstract: The spaces of sequences obtained by Kizmaz have been extended for a sequence $p=(p_k)$ of strictly positive numbers, and their KötheToeplitz duals have also been obtained. Furthermore, we study the matrix transformations of these sequence spaces. Keywords: $\Delta$bounded, $\Delta$convergent, and $\Delta$null sequences, KötheToeplitz duals, matrix transformations Classification (MSC2000): 40C05, 40D05, 40H05 Full text of the article:
