Research output: Contribution to journalArticlepeer-review


This paper deals with (1, 1; r)-convexity of sequences. First, we prove several results on the sets of (1, 1; r)-convex sequences for various values of r. Then we show that the Cesàro matrix does not preserve (1, 1; r)-convexity of sequences for any r≥ 2.
