K. Lust et al., AN ADAPTIVE NEWTON-PICARD ALGORITHM WITH SUBSPACE ITERATION FOR COMPUTING PERIODIC-SOLUTIONS, SIAM journal on scientific computing, 19(4), 1998, pp. 1188-1209
This paper is concerned with the efficient computation of periodic orb
its in large-scale dynamical systems that arise after spatial discreti
zation of partial differential equations (PDEs). A hybrid Newton-Picar
d scheme based on the shooting method is derived, which in its simples
t form is the recursive projection method (RPM) of Shroff and Keller [
SIAM J. Numer. Anal., 30 (1993), pp. 1099-1120] and is used to compute
and determine the stability of both stable and unstable periodic orbi
ts. The number of time integrations needed to obtain a solution is sho
wn to be determined only by the system's dynamics. This contrasts with
traditional approaches based on Newton's method, for which the number
of time integrations grows with the order of the spatial discretizati
on. Two test examples are given to show the performance of the methods
and to illustrate various theoretical points.
