Encyclopedia > Enrico Betti

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 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 Brioschi and Casorati, meeting 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.

Betti (243 words)
Betti studied at the University of Pisa, later was to become a professor (1857) and rector there and director of its teacher's college.
Betti extended and gave proofs relating to the algebraic concepts of Evariste Galois.
Betti thus made an important contribution to the transition from classical to modern algebra.
