Sulle interazioni dei campi di gauge di spin arbitrario
  This manuscript describes in some detail the basic features of higher-spin gauge fields. After presenting some introductory material, I turn to the different formulations available at the free level and finally end with a discussion of the Vasiliev equations in four dimensions based on spinor oscillators.   From the Laurea Thesis defended at the University of Rome "Tor Vergata" on July 2004 (in Italian) .
