Existence of radially symmetric patterns for a diffusion problem with variable diffusivity
We give a sufficient condition for the existence of radially symmetric stable stationary solution of the problem $u_t=\operatorname{div}(a^2\nabla u)+f(u)$ on the unit ball whose border is supplied with zero Neumann boundary condition. Such a condition involves the diffusivity function $a$ and the t...
