Felice Casorati
Felice Casorati (December 17, 1835 – September 11, 1890) was an Italian mathematician who studied at the University of Pavia. He was born in Pavia and died in Casteggio.
Work
He is best known for the Casorati-Weierstrass theorem in complex analysis. The theorem, named for Casorati and Karl Theodor Wilhelm Weierstrass, describes the remarkable behavior of holomorphic functions near essential singularities.
The Casorati matrix is useful in the study of linear difference equations, just as the Wronskian is useful with linear differential equations. It is calculated based on n functions of the single input variable.
