NUMERICAL SOLUTION OF CAUCHY SINGULAR INTEGRAL EQUATIONS WITH HILBERT KERNEL ON THE CIRCLE
摘要
Abstract
In this paper,we first investigate the composite trapezoidal rule for the evaluation of Cauchy principle value integral with Hilbert kernel on a circle.By using continuous piecewise linear function to approximate density function,we get the error estimation of numerical integral.Then we apply the rule to construct two schemes for solving the relevant singular integral equation.Some numerical experiments are presented to confirm the theoretical analysis at last.关键词
