The course provides an introduction to the theory of distributions with applications to solutions of partial differential equations with constant coefficients, further the Fredholm theorems are discussed for the case of a continuous kernel on a compact set as well as Sturm-Liouville operators on bounded intervals, and applications of the separation of variables method to the solution of some boundary value problems and mixed problems.


Basic courses of Calculus and Linear Algebra (in the extent of the courses 01MA1, 01MAA2-4, 01LA1, 01LAA2 held at the FNSPE CTU in Prague).

Syllabus of lectures:

The generalized Laplace transformation. 4. The Fredholm theorems for integral operators with continuous kernels on a compact set. 5. Elliptic operators, Sturm-Liouville operators on a bounded interval, the Green function. 6. Solutions of a boundary value problem for the Laplace equation on a symmetric domain. 7. Solutions of a mixed problem by the separation of variables method.

1. Classification of partial differential equations of second order. 2. Exercises focused on the calculus with distributions - the limit, the differential calculus, an expansion into a Fourier series. 3. Derivative of a piece-wise smooth function. 4. Fundamental solutions for the most common partial differential operators with constant coefficients. 5. Examples of convolutions. 6. Applications of the theory of distributions to solutions of ordinary differential equations with constant coefficients, the wave equation and the heat equation. 7. Examples on the generalized Fourier transformation. 8. Examples on the generalized Laplace transformation with applications. 9. Solutions of integral equations with degenerate kernels. 10.

Study Objective:

Knowledge of the theory of distributions including the Fourier transformation and the Laplace transformation, knowledge of basic results concerning the solvability of integral equations with continuous kernels (Fredholm's theorems), furthermore some basic results about elliptic operators, particularly about Sturm-Liouville operators. Skills to apply this knowledge in solving the most common problems with partial differential operators as well as in solving integral equations.
