Although lectures in mathematics had been delivered since Moscow State University was founded in 1755, the mathematical and physical department was founded only in 1804. . The Mathematics and Mechanics Department was founded on 1 May 1933 and comprised mathematics, mechanics and astronomy departments (the latter passed to the Physics Department in 1
Many mathematical problems have been stated but not yet solved. These problems come from many areas of mathematics, such as theoretical physics, computer science, algebra, analysis, combinatorics, algebraic, differential, discrete and Euclidean geometries, graph theory, group theory, model theory, number theory, set theory, Ramsey theory, dynamical systems, and partial differential equations.
Linear multistep methods are used for the numerical solution of ordinary differential equations.Conceptually, a numerical method starts from an initial point and then takes a short step forward in time to find the next solution point.
Sofia Kovalevskaya, first woman professor in Northern Europe and Russia, the first female professor of mathematics, discovered the Kovalevskaya top; Mikhail Kravchuk, developed the Kravchuk polynomials and Kravchuk matrix; Mark Krein, developed the Tannaka–Krein duality, Krein–Milman theorem and Krein space, Wolf Prize winner
Arnold (left) and Russia's president Dmitry Medvedev. Lenin Prize (1965, with Andrey Kolmogorov), [58] "for work on celestial mechanics." Crafoord Prize (1982, with Louis Nirenberg), [59] "for their outstanding achievements in the theory of non-linear differential equations."

This machine was capable of solving inhomogeneous differential equations. [4] The first versions of Lukyanov's integrators were rather experimental, made of tin and glass tubes, and each integrator could be used to solve only one problem. In the 1930s it was the only computer in the Soviet Union for solving partial differential equations.
The scheme is always numerically stable and convergent but usually more numerically intensive than the explicit method as it requires solving a system of numerical equations on each time step. The errors are linear over the time step and quadratic over the space step: Δ u = O ( k ) + O ( h 2 ) . {\displaystyle \Delta u=O(k)+O(h^{2}).}
Difference equations are similar to differential equations, but replace differentiation by taking the difference between adjacent terms; they can be used to approximate differential equations or (more often) studied in their own right. Many questions and methods concerning differential equations have counterparts for difference equations.
