Nonlocal reaction-diffusion
equations of the
form $
u_t=u_{xx}+F(u,a(u))$, where $a(u)=\int_{-1}^1 u(x)dx$, are considered
together with Neumann or Dirichlet boundary conditions.
One of the
main results deals with linearizations at equilibria. It
states that
for any given set of complex numbers one can
arrange, choosing the
equation properly, that this set is contained in the spectrum
of the
linearization. The second main result shows that
equations of the
above form can undergo a supercritical Hopf bifurcation leading
to an
asymptotically stable periodic solutions.
