WebSep 20, 2024 · In this paper, we study the delayed reaction–diffusion Schnakenberg systems with Neumann boundary conditions. Sufficient and necessary conditions for the occurrence of Turing instability are obtained, and the existence of Turing, Hopf and Turing–Hopf bifurcation for the model are also established. Furthermore, for Turing–Hopf … WebDiffusional-thermal instability of difusion flames 277 diffusive transport zones in the diffusion flame. For large fl, the reaction-zone scales are shorter, and therefore the …

WebMar 10, 2016 · We investigate two-variable reaction-diffusion systems of the hyperbolic type. A linear stability analysis is performed, and the conditions for diffusion-driven instabilities are derived. Two basic types of eigenvalues, real and complex, are described. Dispersion curves for both types of eigenvalues are plotted and their behavior is analyzed. The real … WebJan 3, 2024 · It is proven that wave instability may occur in a two-species hyperbolic reaction–diffusion system with identical inertia if the diffusion coefficients of the species are nonidentical but cannot occur if diffusion coefficients are identical. ... “ Diffusive instabilities in hyperbolic reaction-diffusion equations,” Phys.
