Derivative-free high-order uniformly accurate schemes for highly oscillatory systems

Abstract: In this paper we address the computational aspects of uniformly accurate numerical methods for solving highly oscillatory evolution equations. In particular, we introduce an approximation strategy that allows the construction of arbitrary high-order methods using solely the right-hand side of the differential equation. No derivative of the vector field is required, while uniform accuracy is retained. The strategy is then applied to two different formulations of the problem, namely the two-scale and the micro–m… Show more

“…HOODESolver.jl provides software implementations of several theoretical ideas contained in the recent literature around the so-called two-scale method. In particular, a very recent extension proposed in (Philippe Chartier et al, 2021) enables to reach high order accuracy. The implementation focuses on a multistep method (namely Adams-Bashforth method) coupled with a spectral method for the discretization of the additional variable representing the fast scale.…”

“…The theory developed therein is however of no relevance for the construction of micro-macro decompositions as it relies heavily on trees and associated elementary differentials which can hardly be computed in practice. Our approach actually shares more similarities with the one introduced for highly-oscillatory problems in [CLMV19] and later modified to become amenable for actual computations at any order [CLMZ20]. As a matter of fact, the technical arguments that sustain decomposition (1.4) are essentially adapted from [CCMM15] in a way that will be fully explained in Section 3.…”

“…This restriction becomes prohibitive for small values of ε. We will follow the strategy adopted in [5,6,7,12,13] although in the different contexts of Vlasov-Poisson equations, Klein-Gordon and nonlinear Schr 'odinger equations, to obtain a robust scheme that is able to deal with a large range of ε ∈ (0, 1] (being small or not), since our goal is to obtain a numerical scheme that is uniformly accurate in ε.…”
