Breathers for the Sine-Gordon equation,The problem of breathers, solutions of a nonlinear homogeneous wave equation that are nontrivial, time-dependent and T-periodic is considered. A manifold of such solutions is shown to exist in a distributional sense and some qualitative properties of these solutions are described.

Switching systems and periodicity,nt condition is obtained for the existence of . solutions. The significance for this theory of certain . on the switching surface is shown by an example with . periodic solutions. Further discussion is presented for the important case of ., including a new existence theorem.
