Calculus of Variations (FSI-S1M)

Academic year 2020/2021
Supervisor: doc. RNDr. Miroslav Kureš, Ph.D.  
Supervising institute: ÚM all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:
Students will be made familiar with fundaments of variational calculus. They will be able to apply it in various engineering tasks.
Learning outcomes and competences:
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.
Course contents:
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.
Teaching methods and criteria:
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
Controlled participation in lessons:
Seminars: required
