The propagation of virus infection fronts has been typically modeled using a set of classical (noncohabitation) reaction–diffusion equations for interacting species. However, for some single-species systems it has been recently shown that noncohabitation reaction–diffusion equations may lead...

The dynamical evolution of a deterministic epidemic model is studied. We model the system by taking into account an intermediate class of population, say infected, which after a latency period enter into the infectious class. A mortality rate induced by the disease is also considered. The system...

In this paper we analyze the speed of gas flames in a combustion premixed model that consists of two species (fuel and non-fuel). The main novelty with respect to recently published papers is that here we take into account the effect of the diffusion velocities in the energy equation. This means...

We derive new expressions to estimate the burning velocity of a laminar gas flame in a simplified combustion model based on a one-step single reaction with transport coefficients (mass and heat) depending on temperature, and species with different specific heats. These new expressions generalize...
