Objectives of the study of the discipline

Familiarization of students with the main ways of mathematical formalization of conflict situations in the economic and social spheres and the principles of their solution.

Training in various effective ways to resolve conflict situations, taking into account the interests of the conflicting parties.

Increase the overall level of mathematical culture and improve the skills of using mathematical methods to solve applied problems.

As a result of studying the discipline, the trainee must know:

  • Definition of the generalized function;
  • convergence of sequences of generalized functions;
  • definition of the derivative of a generalized function;
  • Is the product of a generalized function by a smooth function;
  • definition of the convolution of a generalized function;
  • basic examples of singular generalized functions;

be able to:

  • check the convergence of sequences of generalized functions;
  • find the derivatives of given generalized functions;
  • to build fundamental solutions for the simplest differential equations;


  • basic concepts of the theory of generalized functions;
  • actions with generalized functions.
