Resumen:
We consider a finite number of particles that move in Z as independent random walks. The particles are of two species that we call a and b. The rightmost a particle becomes a b particle at constant rate, while the leftmost b particle becomes a particle at the same rate, independently. We prove that in the hydrodynamic limit the evolution is described by a non linear system of two PDE´s with free boundaries.
