Interacci\'on `Oscilador' de Part\'{\i}culas Relativistas
  This is a brief introduction on the graduate level to mechanics of various spin relativistic particles with oscillatorlike interaction. This mathematical model proposed by M. Moshinsky could have considerable physical applications for describing processes mediated by tensor fields and in bound state theory.
