The researcher analyzed the Legendre two-variable method to solve Volterra's nonlinear integrative equation of single, binary and three-dimensional. Pointing, the Legendre two-shifting-variable method was studied in detail. He founded some formulas related to Volterra three-dimensional integrative equation. In order to find an approximate solution Volterra equation was converted from type I to type II to reach a linear system of algebraic equations. The researcher presented numerical examples to illustrate the method and its accuracy.

Researcher studied the effects of planting an indium layer 20-200 nm between two slices of 500 nm gallium sulfide using the physical method of fumigation under air pressure. She also studied the effect of planting indium chips on structure and atomic distribution of elements, optical properties and isolation features. As well as impedance spectrum and heat-based electrical properties.
