Abstract:

It is well known that there are sequences that are summable by every Cesàro method ${C_r}\;(r > 0)$ but are not summable by any Euler method ${E_p}\;(0 < p < 1)$. It is proved here that on the other hand there are sequences that are summable by every Euler method ${E_p}\;(0 < p < 1)$ but are not summable by any Cesaro method.
