Course detail

Calculus of Variations

FSI-S1M Acad. year: 2020/2021 Summer semester

The calculus of variations. The classical theory of the variational calculus: the first and the second variations, conjugate points, generalizations for a vector function, higher order problems, relative maxima and minima and isoperimaterical problems, integraks with variable end points, geodesics, minimal surfaces. Applications in mechanics and optics.

Learning outcomes of the course unit

The variational calculus makes access to mastering in a wide range
of classical results of variational calculus. Students get up apply results
in technical problem solutions.

Prerequisites

The calculus in the conventional ammount, boundary value problems of ODE and PDE.

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.

Assesment methods and criteria linked to learning outcomes

Classified seminar credit: the attendance, the brief paper, the semestral work

Aims

Students will be made familiar with fundaments of variational calculus. They will be able to apply it in various engineering tasks.
