I: Continuity of the set of equilibria. %D 2006 %@ 0022-0396 %U https://hdl.handle.net/20.500.14352/49744 %X We analyze the dynamics of a reaction–diffusion equation with homogeneous Neumann boundary conditions in a dumbbell domain. We provide an appropriate functional setting to treat this problem and, as a first step, we show in this paper the continuity of the set of equilibria and of its linear unstable manifolds. %~
