 Tutor:
 Stanislav Kračmar
 Supervisor:
 Department of Technical Mathematics
 Synopsis:

The course contains the notion of the weak formulation of the boundary problem for the linear elliptic equation of the 2nd order, the concept of the weak solution.
The essential topics are LaxMilgram's lemma, the theorem on the existence and uniqueness of a weak solution. Equivalence of the mentioned boundary problem and a problem of finding the minimum of a suitable quadratic functional.
Galerkin and Ritz's method of finding an approximate solution.
Fundamentals of vector field theory, div, rot operators and their properties, Gauss theorem, Stokes theorem, Weyl's vector field decomposition to the sum of the ∇φ field and the rot w field, Helmholz's decomposition, and related issues.
Euler, Stokes, Oseen and NavierStokes equations for an incompressible fluid. Classical and weak formulations of the boundary problem in the stationary case and mixed initialboundary problems in the nonstationary case for the NavierStokes equations.
