A bifurcation problem for a nonlinear partial differential equation of parabolic type †

We Consider the boundary value problem [d] Here λ is a non negative parameter; f is a given real valuede function defined and a class C2 [d] is an arbitrarily specified function of class C1 on [0, n] satisfying [d] = 0. Under suitable hypotheses concerning f, we investigate the existence and stability properties of stationary solutions for (*). Our approach is to interpret (*) as a dynamical system in an appropriately chosen Banach space, and then to apply to (*) certain known results in the theory of Liapunov stability for general dynamical systems
