Synopsis:

: Principles of mathematical modelling by means of partial differential equations (PDE?s) and introduction to classical and modern theory of PDE?s. The modern theory is ilustrated on 2nd order elliptic PDE?s and on PDE?s appearing in mathematical models used in fluid mechanics.

Requirements:
Syllabus of lectures:

1. Principles of application of PDE?s to description of states and processes in continuum. The procedure of derivation of the transport equation, the heat equation and the equation of continuity.

2. The procedure of derivation of the Navier-Stokes equations, the wave equation, the Lame equations and the Maxwell equations.

3. Usage of the Laplace equation and the Poisson equation in mathematical models.

4. 1st order PDE?s - formulation of an initial or boundary-value problem, the principle of analytic solution.

5. Harmonic functions and their properties (the mean value theorem, the maximum principle).

5. Introduction to classical theory of PDE?s of the elliptic type, the Laplace and the Poisson equation, the role of the volume potential, the single-layer potential and the double-layer potential.
