Abstract:We consider a class of m-point (m > 3) second order boundary value problem (PF\cal{P}_{F}) in a separable Banach space E of the form W 2, 1E(0, 1])W ^{2, 1}_E(0, 1])-solutions of (PF\cal{P}_{F}) is compact and is a retract in C1E(0, 1])C^1_E(0, 1]). A new existence result of W 2, 1E(0, 1])W ^{2, 1}_E(0, 1])-solutions and a related relaxation problem are also provided, here F is no longer bounded.
