S. Wang et al., REACTION-DIFFUSION SYSTEMS WITH NONLINEAR BOUNDARY-CONDITIONS, Zeitschrift fur angewandte Mathematik und Physik, 48(6), 1997, pp. 994-1001
This paper deals with the existence and nonexistence of global positiv
e solutions of reaction diffusion systems with nonlinear boundary cond
itions. Necessary and sufficient conditions on the global existence of
all positive solutions are obtained.
