Equations d'évolution non locales et problèmes de transition de phase

, 2013
The aim of this thesis is to study the large time behavior of solutions of nonlocal evolution equations and to also study the singular limit of equations and systems of parabolic partial differential equations involving a small parameter epsilon.

Asymptotic Consistency Of The Polynomial Approximation In The Linearized Plate Theory. Application To The Reissner-Mindlin Model

, 1997
. We establish a partial link between two standard methods for deriving plate models from linearized three-dimensional elasticity: the asymptotic method, known to justify the Kirchhoff-Love model, and the polynomial reduction method.

Persistence of a unique periodic wave train in convecting shallow water fluid

Demonstratio Mathematica
The coexistence of a traveling pulse and a periodic traveling wave was established in a convecting shallow water model when taking a nonlinear buoyancy term uuxu{u}_{x}.

Exact difference approach on the Shishkin mesh for solving time fractional singularly perturbed parabolic PDE

Partial Differential Equations in Applied Mathematics
A novel approach has been introduced to address time-fractional singularly perturbed parabolic partial differential equations. This method utilizes the L1-Caputo finite difference technique to approximate the fractional derivative term and employs an ...

Pattern formation for a reaction-diffusion system: Catalytic-dependent diffusion coefficients

, 1994
Se considera un modelo de reacción-difusión para dos reactantes en presencia de un tercero, que actúa de catalizador. La escala temporal para el catalizador se compara con la de los reactantes y los coeficientes de difusión dependen solamente de la ...

Uniform convergence of adversarially robust classifiers

European Journal of Applied Mathematics
In recent years, there has been significant interest in the effect of different types of adversarial perturbations in data classification problems. Many of these models incorporate the adversarial power, which is an important parameter with an associated

Low And High Field Scaling Limits For The Vlasov- And Wigner-Poisson-Fokker-Planck Systems

, 1999
This paper is concerned with scaling limits in kinetic semiconductor models. For the classical Vlasov-Poisson-Fokker-Planck equation and its quantum mechanical counterpart, the Wigner-Poisson-Fokker-Planck equation, three distinguished scaling regimes ...
