Learning students of basic concepts, facts and methods of ordinary and partial differential equations. Obtaining the ability to solve certain types of ordinary differential equations, systems of ordinary and partial differential equations. Preparation for courses in which physical phenomena are modeled by differential equations.
Mathematical analysis I and II and algebraic and geometric methods in physics
1. Reminder of basic notions of ordinary differential equations, definition, types of ordinary differential equations, general and particular solutions, initial problem, geometric interpretation. Equations solvable in elementary way, homogeneous, with separable variables, equation with integrating factor, Bernoulli equation, Riccati equation.
2. Basic properties of solutions of linear first order differential equations: linear space of homogeneous solutions, its dimension, base - fundamental system, Wronski matrix and its determinant, solving systems of homogeneous linear equations with constant coefficients.
3. Solving the higher order linear equations with analytical coefficients using the power series - some special functions.
4. Basic concepts of partial differential equations: definition, examples, order; linear, semi-linear, quasi-linear, nonlinear differential equations.
5. First-order partial differential equations: relationship with ordinary equations, method of characteristics.
6. Classification of partial differential equations of order two of two independent variables.
7. Laplace and Poisson equations.
8. Fourier method of variable separation. Initial problem of thermal conductivity equation with periodic boundary conditions
9. Wave equation.
10. Soliton equations: dispersion and nonlinear wave equations, various forms of KdV equations, various types of solutions and their properties, infinitely many conservation laws and integrability of KdV.
Conventional lecture illustrated with examples of the use of equations in physics solved analytically and with the help of software for symbolic and numerical calculations.
During classes students analyse and solve exercises illustrating the content of the lecture.

Lecture: Positive passing of exam (written). Obtaining a positive grade requires at least 55% of correct answers to the questions and tasks asked.
Classes: Passing condition - positive grades of two written tests on the basis of obtaining at least 55% of points on each of them.
Before taking the exam a student must gain positive grade during the class.
