Matrix transformations on some sequence spaces related to strong Cesàro summability and boundedness. (English)
[J] Appl. Math. Comput. 211, No. 2, 255-264 (2009). ISSN 0096-3003

Recently {\it C. Adydin} and {\it F. Başar} [Appl. Math. Comput. 157, No.~3, 677--693 (2004; Zbl 1072.46007)] studied the matrix domain of a triangular matrix in the sets of sequences that are (i) summable to zero, (ii) summable and (iii) bounded by the Cesàro method of order one. {\it I. J. Maddox} [J. Lond. Math. Soc. 43, 285-290 (1968; Zbl 0155.38802)] introduced and studied the above-mentioned class of sequences by the strong Cesàro method of order 1 with index $p$, $p\geq 1$. Here the authors discuss the class of sequences studied by C. Adydin and F. Basar for the strong Cesàro method of order 1 with index $p$, $p\geq 1$. They also determine the $\beta$-duals of the spaces studied and characterize matrix transformations on them into the sets of bounded, convergent and null sequences.
