Encyclopedia
Nikolay Yakovlevich Sonin (February 22, 1849 – February 27, 1915) was a Russian
mathematician
.
He was born in Tula
and attended Lomonosov University, studying mathematics and physics
there from 1865 to 1869. His advisor was Nikolai Bugaev
. He obtained a Master's Degree with a thesis submitted in 1871, then he taught at the University of Warsaw
where he obtained a doctorate in 1874. He was appointed to a chair in the University of Warsaw
in 1876. In 1894, Sonin moved to St. Petersburg
where he taught at the University for Women.
Sonin worked on special functions
, in particular cylindrical functions. He also worked on the Euler–Maclaurin summation formula.
Other topics Sonin studied include Bernoulli polynomials
and approximate computation of definite integrals, continuing Chebyshev
's work on numerical integration
. Together with Andrey Markov
, Sonin prepared a two volume edition of Chebyshev's works in French
and Russian
. He died in St. Petersburg.

Mathematics
Mathematics is the study of quantity, space, structure, and change. Mathematicians seek out patterns and formulate new conjectures. Mathematicians resolve the truth or falsity of conjectures by mathematical proofs, which are arguments sufficient to convince other mathematicians of their validity...

Other topics Sonin studied include Bernoulli polynomials
Bernoulli polynomials
In mathematics, the Bernoulli polynomials occur in the study of many special functions and in particular the Riemann zeta function and the Hurwitz zeta function. This is in large part because they are an Appell sequence, i.e. a Sheffer sequence for the ordinary derivative operator...
