TAUBERIAN THEOREMS FOR THE PRODUCT OF BOREL AND LOGARITHMIC METHODS OF SUMMABILITY

Abstract

In this paper, we show that if a sequence is summable by the product method B `; k , then it is also summable by the logarithmic method `; k , provided two-sided conditions of Hardy-type are satised. We also obtain some classical Tauberian theorems and their generalizations as special cases of our main theorems.
