On Nonlinear Nonlocal Systems of Reaction Diffusion Equations

Abstract

The reaction diffusion system with anomalous diffusion and a balance lawut+-Δα/2u=-fu,v,   vt+-∆β/2v=fu,v,0<α,β<2, is con sidered. The existence of global solutions is proved in two situations: (i) a polynomial growth condition is imposed on the reaction termfwhen0<α≤β≤2; (ii) no growth condition is imposed on the reaction termfwhen0<β≤α≤2.
