Luigi Bianchi

Luigi Bianchi ( born January 18, 1856 in Parma, † June 6, 1928 in Pisa ) was an Italian mathematician who primarily worked on differential geometry.

He studied in Pisa with Enrico Betti and Ulisse Dini and his friend Gregorio Ricci - Curbastro, which should be a major Differentialgeometer also and also a later colleague in Pisa was. In 1877 he graduated with honors. After his graduation, he went to the universities of Munich and Felix Klein in Göttingen. In 1881 he became a professor at his university in Pisa, the Scuola Normale Superiore, where he received a full professorship in 1890. One of his students was Guido Fubini.

In 1898, he classified the three-dimensional Lie groups of isometries ( distance - preserving mappings ) Riemannian manifolds (and thus the three-dimensional real Lie algebras ). These nine Bianchi groups played a role in the symmetry classification of cosmological solutions of general relativity later. In 1902 he discovered the Bianchi identities for the Riemann curvature tensor (which apparently already Ricci in 1880 discovered what was but forgotten even for himself ), which also play a role in the general theory of relativity ( press the conservation of energy from ). Bianchi was also involved in number theory.

Bianchi was a corresponding member of the Accademia dei Lincei in 1887 and in 1893 a full member ( socio nazionale ) selected. He gave out a long time the Annali di Matematica. In 1924 he became a senator. He was an honorary member of the London Mathematical Society.
