Biography
He studied at the Alexandrinsky Orphan Institute , then entered the Faculty of Physics and Mathematics of Moscow University , which he graduated in 1847 with a candidate’s degree and a silver medal for his work: “Calculation of earth compression from observations using the least squares method”.
He taught mathematics, in 1853-1866, in the Alexandrinsky orphan cadet corps , which was later transformed into the Alexander Military School [3] (1863-1866); then, in 1866-1870, he worked as a teacher and inspector of the 2nd St. Petersburg military gymnasium . After the Council of Moscow University honored Alekseyev with a doctorate in mathematical sciences honoris causa, on September 22, 1871 he was appointed supernumerary ordinary professor at the University of Warsaw in the department of pure mathematics, a year later he was appointed an ordinary professor, in January 1876 he became dean of the Faculty of Physics and Mathematics . At the university, Alekseev read analytical geometry, higher algebra, the theory of definite integrals, the integration of differential equations, and probability theory.
On January 1, 1877, N. N. Alekseev was dismissed from service for his seniority by a current state adviser .
On October 5, 1879, he was elected to the Adjunct of the Academy of Sciences in Physics and Mathematics (pure mathematics) [4] .
Died March 3 (15), 1881 in St. Petersburg. He was buried in the Voskresensky Novodevichy Convent (St. Petersburg).
Scientific Papers
N. N. Alekseev published the first course in integral calculus in Russian; the Academy of Sciences awarded him a half Demidov Prize for this course. In the 1870s, this course appeared as a second edition, significantly supplemented and corrected:
- The beginning of integral calculus / Comp. N. Alekseev, mentor-supervisor at Alexander.-orphans. case. Prince 1-2. - Moscow: type. V. Gauthier, 1861-1862.
- Integral calculus / Comp. Nikolai Alekseev, horde prof. Imp. Warsaw un-that. - 2nd ed. Prince 1. - Moscow: Univ. type of. (Katkov and Co.), 1874 .-- VIII, 368 p.
In his course on analytic geometry, for the first time in Russian, the analytic beginnings of the new geometry of Shal , Mobius and Steiner were presented.
- Analytical geometry on the plane / Comp. N. Alekseev. Vol. 1. - Moscow: type. V. Gauthier, 1865. - [6], 218, 16 p.
As a founding member of the Moscow Mathematical Society, Alekseev took an active part in his work and published a number of articles related to various departments of pure mathematics in the Mathematical Collection. So, in the first volume for 1866 he placed two articles: “Property of integrals of algebraic irrational functions that are expressed by logarithms only” and “Integration of differentials containing a square root of a fourth degree polynomial and differentials containing a cubic root of a third degree polynomial ; in the second volume: Curvilinear orthogonal coordinates, in the application to the study of curvature of curves on various surfaces; in the third volume: “On the values of the integrating factor in determining the form of the integral of a homogeneous differential equation of the first order” and “Studies on functions similar to Legendre functions”.
In 1868, at the first congress of Russian naturalists, Alekseev made a message “On elliptic integrals with various modules”, and at the second congress - “On the integrating factor of first-order and first-degree differential equations”.
- Integration of differential equations / Comp. Doctor of Mathematics N. Alekseev. Vol. 1. - Moscow: Univ. type of. (M. Katkov), 1878.
After being approved by an adjunct, he submitted two remarkable notes to the St. Petersburg Academy of Sciences: one on a very simple method for finding the complete integrals of first-order equations with constant coefficients, and the other:
- On suitable fractions obtained by extracting the square root from an integer polynomial of any degree: (Chit. Nov 11, 1880) / [Op.] N. Alekseeva. - [St. Petersburg]: type. Imp. Acad. Sciences, 1881. - 18 p.
