主 题:long-term numerical integration Newton-Raphson iteration general minimal residual(GMRES) multiple shooting unstable manifold
摘 要:The recent result of an orbit continuation algorithm has provided a rigorous method for long-term numerical integration of an orbit on the unstable manifold of a periodic *** algorithm is matrix-free and employs a combination of the Newton-Raphson method and the Krylov subspace ***,the algorithm adopts a multiple shooting method to address the problem of orbital instability due to long-term numerical *** algorithm is described through computing the extension of unstable manifold of a recomputed Nagata′s lowerbranch steady solution of plane Couette flow,which is an example of an exact coherent state that has recently been studied in subcritical transition to turbulence.
