We prove the existence of u2 and u3 using mountain pass arguments of<br />

the Ambrosetti-Rabinowitz type.<br />

We show the existence of u4 by using Lyapunov-Schmidt arguments to<br />

reduce the solvability of (0.1) to a finite dimensional problem.<br />

We use degree theory to show the existence of u5.<br />
