The billiard is a dynamical system describing the trajectory of an infinitely small particle moving without friction inside a domain bounded by a reflecting wall. When it hits the wall, theparticle is reflected following the optical law of reflection asserting that the angle of incidence= the angle of reflection. When the trajectory repeats itself, we speak of a periodic orbit. Thisthesis is about two generalizations of this classical billiard model : projective and complex billiards. The projective billiards were introduced and studied by Tabachnikov and can be defined as bounded domain whose boundary is endowed with a field of transverse lines. The complex billiards were introduced and studied by Glutsyuk and are a natural generalization ...
