31134 Zurria           Discovered 1997 Sept. 27 at the Osservatorio San Vittore.
Giuseppe Zurria (1810-1896), professor of mathematics at the University of Catania, where he was also dean of the faculty and rector, studied some arguments of analysis, special functions and the development of the perturbative function in series of spherical functions.
