|Abstract: ||In this paper, we rigorously
prove the existence and stability of asymmetric spotty patterns for the Gray-Scott model in a bounded two dimensional domain.
We show that given any two positive integers k_1,\,k_2,
there are asymmetric solutions with k_1 large spots (type A) and k_2 small spots (type B).
We also give conditions for their location and calculate their heights.
Most of these asymmetric solutions are shown
to be unstable. However, in a narrow range of parameters,
asymmetric solutions may be stable.|
