报告摘要:This report is concerned with the numerical solutions of Schrödinger-Boussinesq (SBq) system by an orthogonal spline collocation (OSC) discretization in space and Crank-Nicolson (CN) type approximation in time.To implement the CN+OSC scheme, then we devise a new computation method based on the orthogonal diagonalization techniques (ODT), which can be realized by FFT and is suitable for parallel computation. In order to compare the performance of ODT with other methods, we devise an alternating direction implicit (ADI) method to compute the CN+OSC scheme for high spatial dimension SBq system. As an alternative implementation, the new method ODT not only exhibits more accurate numerical results, but also demonstrates stronger invariance preserving ability. Numerical results are reported to verify the error estimates and the discrete conservation laws.
