Multiple solutions of a Dirichlet problem in one-dimensional billiard space
Jan Tomecek;Abstract
The paper gives multiplicity results for an impulsive boundary value problem. This problem can be understood as a problem in one-dimensional billiard space and it is also a generalization of oscillator with obstacles from below and from above and absolutely elastic impacts. A simple condition for the existence of solution with exact number of impacts is given, as well as the multiplicity result. The results are obtained by a transformation into problem without impulses (without impacts) and using Schauder fixed point theorem.
