Chebyshev 小波求解超奇异积分
Chebyshev wavelets for solving hyper-singular integral
摘要
Abstract
In terms of the hyper-singular integrals numerical calculation problems, this paper uses the Chebyshev wavelets to calculate the hyper-singular integrals which are based on the definition of Hadamard finite-part integrals of the hyper-singular integrals. As the Chebyshev wavelet has the properties of orthogonality, the explicit expression and the computability of wavelet function, the singular point in the hyper-singular interval can be transformed into the endpoints of interval, and subsequently, the hyper-singular integral can be computed by using the definition of Hadamard finite-part integral where the hyper-singular point is located at the endpoints of interval. The study examples demonstrate the validity and applicability of the proposed technique.关键词
