Abstract:

In this paper we extend the Jakimovski $[J,f(x)]$ means to double sequences. We call the new means the $[J,f(x,y)]$ means. We characterize such $f$’s that give rise to regular and to totally regular $[J,f(x,y)]$ means. We also give a necessary and sufficient condition for representability of a function $f(x,y)$ as a double Laplace transform with a determining function of bounded variation in two variables.
