Sarvadaman Chowla

from Wikipedia, the free encyclopedia

Sarvadaman Chowla (born October 22, 1907 in London , † December 10, 1995 in Laramie , Wyoming ) was an Indian mathematician who dealt with number theory, analysis and combinatorics.

He was born in London because his father Gopal Chowla, later professor in Lahore , studied at Cambridge University . Chowla returned to India with the family, where he studied at Government College in Lahore (Master's degree in 1928). He then went to Cambridge University, where he received his doctorate in 1931 under John Edensor Littlewood . Chowla has taught at various universities in India: St Stephen's College in Delhi , Banaras Hindu University in Benares , Andhra University in Waltairand from 1936 to 1947 as chairman of the mathematics faculty at the Government College of Punjab in Lahore. In 1947 he went to the USA to escape the turmoil of the civil war after independence, which led to violent clashes in Punjab . Until 1949 he was at the Institute for Advanced Study , then professor at the University of Kansas in Lawrence (Kansas) . In 1952 he went to the University of Colorado at Boulder . From 1963 he was a professor at Pennsylvania State University , where he stayed until his retirement in 1976.

Chowla published a large number of papers e.g. B. in additive number theory (Waring problem, partitions), analytical number theory (Riemann zeta function, Epstein zeta function, Dirichlet functions etc.), quadratic forms, class numbers of different algebraic number fields, Bernoulli numbers, Diophantine equations, elliptic integrals, Latin squares , trigonometric sums, Chowla conjecture . The Bruck-Chowla-Ryser theorem (1950) in the theory of block plans (and finite projective planes) and the Ankeny-Artin-Chowla theorem about the class number of real square number fields are named after him and Herbert Ryser , Richard Bruck .

He published u. a. with Harold Davenport , Emil Artin and Nesmith Ankeny , Atle Selberg , Helmut Hasse , Louis Mordell , Thoralf Skolem , Paul Erdős , Marshall Hall , Gorō Shimura , Hans Zassenhaus , Richard Brauer .

He was a member of the Indian Academy of Sciences and received the Padma Bhushan . He was an honorary member of the Norwegian Academy and a member of the London Mathematical Society . In 1950 he was invited speaker at the International Congress of Mathematicians in Cambridge (Massachusetts) and in 1962 he gave a lecture at the ICM in Stockholm ( Elementary remarks on the zeta function of an algebraic variety ).

His doctoral students include John Friedlander and, in India, RP Bambah (* 1925), who researched the geometry of numbers and was a professor at the University of Chandigarh.
