(10382) Hadamard Main-belt Asteroid
Discovered on 15 September 1996 by P. G. Comba at Prescott.
Named in honor of the eminent French mathematician Jaques-Salomon Hadamard (1865-1963). Hadamard made major contributions to the theory of functions of a complex variable and the study of the partial differential equations of mathematical physics. In 1896 he gave a proof of the prime number theorem that defines the frequency of prime numbers among the integers.Naming citation (19990728/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
