Equations of Mathematical Physics II

FSI-9RF2Acad. year: 2016/2017Winter semesterNot applicable.. year of study1  credit

The course is a free continuation of subject Equations of Mathematical Physics I.
It focuses on modern methods of solving linear and nonlinear differential equations.
By means of functional analysis generalized formulation of stationary boundary value problems is introduced and existence of their solution is studied.
Finite dimensional approximations of solutions being base for numerical solving are introduced, too.

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline.

Assesment methods and criteria linked to learning outcomes

Practical part of the examination tests ability of mutual conversion of the weak, variational and classical formulation of the particular nonlinear boundary value problem and analysis of its generalized solution. The theoretical part consists of 3 questions related to the subject-matter presented at the lectures.
