內(nèi)容介紹:Oscillatory integral transforms appear in many physical problems and their computation with traditional quadrature rules will be expensive when the oscillation of frequency is large. Complex Gaussian quadrature rules, which were developed by Asheim and Huybrechs in 2013, enjoy an attractive advantage that they have optimal asymptotic order. However, their existence remains an issue. In this talk, I will introduce new complex generalized Gauss-Radau quadrature rules for Hankel transforms of integer order and show that such quadrature rules can be constructed with theoretical guarantees.
