Abstract

In this work we consider the nonlocal evolution equation (∂ u(w,t))/(∂ t)=-u(w,t)+ ∫S1J(wz-1)f(u(z,t))dz+ h, h > 0 which arises in models of neuronal activity, in L2(S1), where S1 denotes the unit sphere. We obtain stronger results on existence of global attractors and Lypaunov functional than the already existing in the literature. Furthermore, we prove the result, not yet known in the literature, of lower semicontinuity of global attractors with respect to connectivity function J.
