Transitions between nonsymmetric and symmetric steady states near a triple eigenvalue [PDF]
, 1983 We examine the existence of nonuniform steady-state solutions of a certain class of reaction-diffusion equations. Our analysis concentrates on the case where the first bifurcation is near a triple eigenvalue.
