(1837 - 1908).
He graduated from the course in Physics and Mathematics at St. Petersburg University. He received a master's degree for his thesis: "Determination of arbitrary functions in integrals of linear partial differential equations, Ph.D. - for his thesis:" On the set of equations with partial derivatives and some problems of mechanics ". A professor at St. Petersburg University, read the differential and integral calculus in Mykolaiv Marine Academy. - Scientific work Korkina are subject, mainly the integration of partial differential equations and number theory. The first area included his master's and doctoral theses, and articles "Sur le theoreme de Poisson et son reciproque" ( "Bulletin de l, Acad. de St.-Petersb. ", Volume XVI, 1871)," On partial differential equations of second order "(Annex to the minutes of the University, 1878) and other. In theory, the numbers of Korkina focus on the theory of quadratic forms. The main question of the so-called exact limit for a minimum of certain quadratic forms, are easily solved for the binary form, was already difficult for ternary forms, and more to form with four or more variables. From 1871 to 1877 Korkin, together with E.I. Zolotarev, undertook a series of studies on this issue, and they managed to find solutions for forms with four and five variables. These results, capital in the theory of definite quadratic forms, described in articles published in the "Mathematische Annalen" (Volume V, VI and XI). - A detailed list of works Korkina gave KA. Posse (Journal of the Ministry of National Education, 1908, November).
