Abstract
The regular solutions of generalized axisymmetric potential equation\(\frac{{\partial ^2 u}}{{\partial x^2 }} + \frac{{\partial ^2 u}}{{\partial y^2 }} + \frac{{2a + 1}}{y} \frac{{\partial u}}{y} = 0\), a>−1/2 are called generalized axisymmetric potentials. In this paper, the characterizations of lower order and lower type of entire GASP in terms of their approximation error {En} have been obtained.
