Boris Alexejewitsch Wenkow ( Russian Борис Алексеевич Венков , English transcription Boris Alekseevich Venkov ; born August 13, 1900 in Kratkowo , today in Pskov Oblast ; † December 13, 1962 in Leningrad ) was a Russian mathematician who dealt with number theory.
Life
Venkov studied at the University of Leningrad with the degree in 1925, was from 1928 to 1934 at the Mathematical Institute of the Academy of Sciences (later the Steklov Institute ), became a professor in 1933 and taught at the University of Leningrad from 1935. In 1936 he completed his habilitation (Russian doctorate).
In 1928 he gave an elementary proof of the class number formulas for imaginary quadratic number fields by Dirichlet using the arithmetic of quaternions and the theory of ternary quadratic forms according to Gauss . In 1940 he published a reduction theory of positive-definite quadratic forms.
