题目: Hopf bifurcation of spike solutions for some Turing systems; 摘要: We use the abstract Crandall-Rabinowitz Hopf bifurcation to the spike solutions of the Gray-Scott system. The existence and stability of  periodic spike solutions are obtained. The core problem in this study is a nonlocal eigenvalue problem.报...
