Carlo Somigliana Carlo Somigliana Carlo Somigliana (20 September 1860 – 20 June 1955) was an Italian mathematician and a classical mathematical physicist, faithful member of the school of Enrico Betti and Eugenio Beltrami. He made important contributions to linear elasticity: the Somigliana integral equation, analogous to Green's formula in potential theory, and the Somigliana dislocations are named after him. Other fields he contribute to include seismic wave propagation, gravimetry and glaciology. One of his ancestors was Alessandro Volta: precisely, the great Como physicist was an ancestor of Carlo's mother, Teresa Volta. Carlo Somigliana began his university studies in Pavia, where he was
