Efficient block collocation methods for highly oscillatory Volterra integral equations with Bessel kernels
摘要
This paper investigates the design and analysis of numerical methods specifically tailored to highly oscillatory Volterra integral equations with Bessel kernels. First, we analyze the oscillatory behavior of the solution by leveraging the resolvent kernel and asymptotic properties of highly oscillatory integrals. Second, we employ the block collocation boundary value method and Filon quadrature rule to discretize the integral equations. Third, we conduct a convergence analysis with respect to the oscillation by examining the collocation error. Finally, we present several numerical examples to illustrate the effectiveness of the proposed methods.
