Abstract

A method of generalized separation of variables allows to decrease complexity of a problem and to represent a solution as a series where each summand depends on every variable independently on others. This method is useful if we can't separate variables by analytic one. In that case we can get an approximate solution with desired property. The most universal method scheme is described in the Voitovich, N. N. et al., (1997). Each step of the method calculates a new member of the series and tries to make the solution of the equation more closely to exact one. In this paper we will deal with three-dimensional integral equations and method of separation of variables for solving it. This method calculates each summand of a series considering minimum of respective functional. Also some numerical results are given

求解三维积分方程的广义分离变量方法
广义分离变量的方法可以降低问题的复杂性,并将解表示为一个级数,其中每个求和依赖于每个变量,而不依赖于其他变量。如果不能用解析法分离变量,这种方法是有用的。在这种情况下,我们可以得到一个近似解。Voitovich, N. N. et al.,(1997)描述了最通用的方法方案。该方法的每一步都计算级数中的一个新成员,并试图使方程的解更接近于精确解。本文将讨论三维积分方程及其解的分离变量法。该方法考虑各函数的最小值来计算级数的和。并给出了一些数值结果
