A nonlocal eigenvalue problem and the stability of spikes for reaction-diffusion systems with fractional reaction rates

, 2003
We consider a nonlocal eigenvalue problem which arises in the study of stability of spike solutions for reaction-diffusion systems with fractional reaction rates such as the Sel'kov model, the Gray-Scott system, the hypercycle Eigen and Schuster ...
