Enrico Betti

From Wikipedia, the free encyclopedia

Enrico Betti (21 October 1823 - 11 August 1892) was an  Italian mathematician, now remembered mostly for his 1871 paper on topology that led to the later naming after him of the Betti numbers. He worked also on the theory of equations, giving early expositions of Galois theory. He also discovered Betti's theorem, a result in the theory of elasticity.

He was born in Pistoia, Tuscany. He graduated from the University of Pisa in 1846. After a time teaching, he held an  appointment there from 1857. In 1858 he toured Europe with Francesco Brioschi and  Felice Casorati, meeting Bernhard Riemann. Later he worked in the area of theoretical physics opened up by Riemann's work. He was also closely involved in academic politics, and  the politics of the new Italian state.
