Person: Cherubino, Salvatore
Salvatore Cherubino was an Italian mathematician who worked on algebraic geometry and probability theory.
Mathematical Profile (Excerpt):
- Immediately after he graduated, Cherubino attended a course given by Pascal on classical binary forms.
- This led to Cherubino publishing the paper Ampliamento di un sistema completo alle cui forme fondamentali si aggreghi una nuova forma di ordine n Ⓣ(Addition of a complete system to whose basic forms aggregates is a new form of order n) (1911) in Battaglini's Giornale di matematiche.
- Cherubino was awarded a government scholarship for advanced study which allowed him to attend the courses of Levi-Civita and Veronese while, advised by Severi, he devoted himself to the study of algebraic geometry.
- This led to Cherubino publishing Sulle curve iperellittiche con trasformazioni birazionali singolari in sé e sui loro moduli algebrici Ⓣ(On hyperelliptic curves with singular birational transformations in themselves and their algebraic forms) (1913-14).
- In 1913 Cherubino was appointed as an assistant to the Chair of Infinitesimal Calculus at the University of Naples but he continued to teach in secondary schools.
- Cherubino was drafted into the military, first as a private soldier and then, at his request, as an officer in the Territorial Militia where he served as an telegraphic engineer.
- Cherubino remained with his unit until the end of the war.
- At Naples, Cherubino was influenced by Gaetano Scorza who taught at the University of Naples from 1920 to 1934.
- Cherubino was again influenced by Pascal and he began to undertake research on a new topic, publishing Sulle varietà abeliane reali e sulle matrici di Riemann reali Ⓣ(On Abelian real varieties and real Riemann matrices) in 1922.
- However, Cherubino now studied Civil Engineering and was awarded his laurea in that topic in 1923 and began lecturing in mathematics at the industrial technical institute in Naples.
- Cherubino published several important memoirs on matrix theory around this time such as Le matrici riemanniane sottonormali (1927), Le matrici caratteristiche delle simmetrie sulle varietà abeliane reali Ⓣ(The matrices characteristics of symmetries on the real Abelian varieties) (1928) and Una applicazione del calcolo delle matrici alla teoria delle forme quadratiche Ⓣ(An application of the calculation of the matrices to the theory of quadratic forms) (1929).
- In 1933, approaching the age of fifty, Cherubino won the competition for the Chair of Analytical, Projective and Descriptive Geometry and Drawing at the University of Messina.
- After retiring, Cherubino published the monograph Calcolo dell Matrici Ⓣ(Calculation of matrices) (1957).
- The memory of Salvatore Cherubino remains deep in the hearts of all his students and we regret losing his counsel but we are committed to follow his example.
- As well as the gold medal which Passaquindici mentions, Cherubino was honoured with election to the Accademia Pontaniana di Napoli in 1928 and to the Accademia Leonardo da Vinci di Napoli in 1932.
Born 3 June 1885, Naples, Italy. Died 2 August 1970, Pisa, Italy.
