Spontaneous oscillations in two 2-component cells coupled by diffusion. (English) Zbl 0588.92002
Mathematical examples are presented of oscillators with two variables which oscillate stably when coupled with a twin via diffusion. The mathematical method is a type of singular perturbation theory combined with bifurcation theory.
It is shown that all stationary solutions are unstable for appropriate parameter settings. Numerical examples are presented.
