Reactive diffusion
WebBlowup in Reaction-Diffusion Systems with Dissipation of Mass* Michel Pierret Didier Schmittt Abstract. We prove possible blowup in finite time of the solutions to reaction-diffusion systems which preserve nonnegativity and for which the total mass of the components is nonincreasing in time (two natural properties in applications). WebIn facilitated diffusion, molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers. A concentration gradient exists …
