On the side of integral equation formulations, advancements in deriving Fredholm integral equations of the second kind have enhanced the numerical stability and accuracy of electromagnetic field ...

The characteristic functions satisfying (2) below are proved to be essentially the semi-stable laws. Auxiliary simultaneous integral equations are studied in Theorems 1, 2, 2' and 3.

Under investigation in this paper is a (2+1)-dimensional nonlinear Schrödinger equation (NLS), which is a generalisation of the NLS equation. By virtue of Wronskian determinants, an effective method ...
