Multiplicity results for a third order boundary value problem at resonance. (English) Zbl 0932.34014
The author deals with the boundary value problem $x'''+ k^2x'+ g(x,x')= p(t),\quad x'(0)= x'(\pi)= x(\eta)= 0,$ where $$\eta$$ is fixed, and the nonlinearity $$g$$ is bounded. Existence and nonuniqueness of solutions are studied together with the structure of the solution set.
