Liouville Operator Approach to Symplecticity-Preserving Renormalization Group Method
arXiv:nlin/0309021 · doi:10.1016/j.physd.2004.02.004
Abstract
We present a method to construct symplecticity-preserving renormalization group maps by using the Liouville operator, and obtain correctly reduced symplectic maps describing their long-time behavior even when a resonant island chain appears.
