Hybrid Trigonometric Varieties
A. Lastra, J. Rafael Sendra, J. Sendra
In this paper we introduce the notion of hybrid trigonometric parametrization as a tuple of real rational expressions involving circular and hyperbolic trigonometric functions as w…

Multiscale Gevrey asymptotics in boundary layer expansions for some initial value problem with merging turning points
Alberto Lastra, Stéphane Malek
We consider a nonlinear singularly perturbed PDE leaning on a complex perturbation parameter . The problem possesses an irregular singularity in time at the origin and involves…

Gevrey multiscale expansions of singular solutions of PDEs with cubic nonlinearity
Alberto Lastra, Stéphane Malek
We study a singularly perturbed PDE with cubic nonlinearity depending on a complex perturbation parameter . This is the continuation of a precedent work by the first author. We…
