The aim of this paper is twofold. On one hand we prove that the Moreau's sweeping processes driven by a uniformly prox-regular moving set with local bounded retraction have a unique solution provided that the coefficient of prox-regularity is larger than the size of any jump of the driving set. On the other hand we show how the case of local bounded retraction can be easily reduced to the 1-Lipschitz continuous case: indeed we first solve the Lipschitz continuous case by means of the so called "catching-up algorithm", and we reduce the local bounded retraction case to the Lipschitz one by using a reparametrization technique for functions with values in the family of prox-regular sets.
Keywords: Evolution variational inequalities, functions of bounded variation, sweeping processes, prox-regular sets, retraction, geodesics with respect to the excess.
