摘要
讨论了核为(x-s)-3的强奇异积分 f(x)(x-s)-3dx的Hadamard有限部分积分f·p·(f(x))/((x-s)3)dx,在区间[a,b]上将f(x)用分片二次Lagrange插值多项式fQ(x)代替的数值求积的新的误差估计,并给出详细证明。
Discussed is the Hadamard finite-part integral of a kind of hypersingular integral with the kernel. A new error of numerical integration is given which is approximated by its Lagrange quadratic interpolation function inand then detailed proof is given.
