Orthogonal Polynomial Solving Method of General Singular Dual Integral Equations

Based on the method of Jacobi orthogonal polynome, general singular dual integral equations are expressed as the series of Jacobi orthogonal polynome on n order. The general singular dual integral equations are changed into linear algebraic equations by Jacobi orthogonal polynome. Thus general solutions are given through solving unknown coefficient of every term in the series. The eqnivalence between singular dual integral equations and by it changed into algebraic equations, existence and non-uniqueness of expressive form on the solutions are proved exactly. In this paper the given theoretical solutions and solving method provides application to problems of solving mixed boundary value of complex mathematics, physics, soft science.
