本文研究了圆周上带希尔伯特核的柯西奇异积分的复合梯型公式.利用连续的分片线性函数逼近被积函数,得到积分公式的误差估计;然后用积分公式构造求解对应奇异积分方程的两种格式;最后给出数值实验验证理论分析结果.
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.
