Triangular Isotropic Reaction-Diffusion Systems: Application to Texture Synthesis

Abstract

This work is devoted to the existence of weak solutions for m × m isotropic reaction-diffusion systems. This type of system appears in texture synthesis. The originality of this study persists in the fact that the non-linearities considered here involve the gradients of solutions with arbitrary growth and initial data are only in L 2 (Ω). For this reason, New techniques are needed to show the consistency of these models is that we present in this study showing the global existence of weak solutions.
