Mathematical Methods in the Applied Sciences, Volume 48, Issue 8, Page 9207-9224, 30 May 2025.ABSTRACT We consider a Maxwell system on ℝ3$$ {\mathbb{R}}^3 $$ with highly oscillating periodic coefficients. It is known that the solutions converge in the weak‐ ∗$$ \ast $$ topology of L∞(0,T;L2(ℝ3))$$ {L}^{\infty}\left(0,T;\kern0.3em {L}^2\left({\mathbb{R}}^3\right)\right) $$ to the solution of a similar problem with constant coefficients given as ...

Chemostat models with Monod and Haldane consumption functions and random environmental fluctuations
Mathematical Methods in the Applied Sciences, Volume 48, Issue 7, Page 7412-7431, 15 May 2025.In this paper, we study the asymptotic dynamics of two chemostat models with random environmental fluctuations modeled by means of real noise, where different consumption functions for the consumer species (Monod and Haldane) are taking into account. For each model, our main goal is to investigate the existence of deterministic attracting sets.

Stochastic COVID‐19 epidemic model incorporating asymptomatic and isolated compartments
Mathematical Methods in the Applied Sciences, Volume 48, Issue 7, Page 8400-8422, 15 May 2025.This study delves into the intricate dynamics of the COVID‐19 epidemic by extending a deterministic compartmental model incorporating asymptomatic, quarantined and isolated compartments, with a stochastic model capturing the natural randomness of the processes.

The assembly and dynamics of ecological communities in an ever‐changing world
Ecological Monographs, Volume 94, Issue 4, November 2024.Abstract Alternative perspectives on the maintenance of biodiversity and the assembly of ecological communities suggest that both processes cannot be investigated simultaneously. In this concept and synthesis, we challenge this view by presenting major theoretical advances in structural stability and permanence theory.

Ecuaciones diferenciales en Física
, 2023 Las ecuaciones diferenciales son fundamentales a la hora de describir y estudiar la dinámica de sistemas físicos. Existen diversos tipos de ecuaciones diferenciales, algunas de las cuales pueden ser resueltas analíticamente de forma que conducen a una solución general (o particular) del problema planteado, mientras que otras requieren la aplicación de ...
