  - In this paper we investigate the existence of closed billiard trajectories in
    not necessarily smooth convex bodies. In particular, we show that if a body K
    ⊂ Rd has the property that the tangent cone of every non-smooth point q ∉ ∂K is
    acute (in a certain sense), then there is a closed billiard trajectory in K.@eng
