Introduction
Abstract
En
In this paper, some basic properties (recurrence relations,asymptotic expansion, series representation and others) are derived for the new function
, which covers certain well-known special functions for particular choices of the parameteres
. For example, for
and
,
one obtains respectively
and
,where(Error rendering LaTeX formula) is the complementary incomplete Gamma function and
is a function of Debye type.The function
has been introduce by us in order to find a class of exact solutions for nonlinear wave equations of the Klein-Gordon type
, where
and a, b are constants.
In this paper, some basic properties (recurrence relations,asymptotic expansion, series representation and others) are derived for the new function
