2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/84155We present the application of variational-wavelet analysis to numerical/analytical calculations of Wigner functions in (nonlinear) quasiclassical beam dynamics problems. (Naive) deformation quantization and multiresolution representations are the key points. We construct the representation via multiscale expansions in generalized coherent states or high-localized nonlinear eigenmodes in the base of compactly supported wavelets and wavelet packets.3 pages, 2 figures, JAC2001.cls, submitted to Proc.
