The aim of this note is to introduce the techniques of exterior differential systems in the context of a problem in billiards. The author generally works in the real analytic category, although all the nonexistence results discussed in the paper imply nonexistence of smooth solutions.For the entire collection see [Zbl 1089.53004].
