Enrollment into the second academic year.

The prerequisite for the theoretical exam is a positive result of the written exam.

Homework may also be one of obligations.

Content (Syllabus outline)

Holomorphic functions: extended complex plane, domains and paths, the Cauchy-Riemann equations, contour integrals, winding number, Cauchy’s formula, Liouvlle’s theorem, Laurent’s and power series, zeros of holomorphic functions, isolated singular points, logarithm and powers, the residue theorem, gamma function, open maps and the maximum modulus principle, Moebius transformations.

Harmonic functions: Poisson’s formula for the disk, harmonic functions in Rˆ3 (Dirichlet’s problem and Green’s function).

Fourier transform: convolution, basic properties , the inverse transform, Plancherel’s theorem, applications (to heat equation).

Power series solutions of differential equations of second order: ordinary and regular singular points, Bessel’s equation and functions, Legendre's equation, polynomials and associated functions, other orthogonal polynomials (Hermite and Laguerre).

Boundary value problems:the vibrating string (Fourier’s method of separation of variables, d’Alembert’s formula), the regular Sturm-Liouville problem, vibration of circular membrane, the Laplace equation on the ball.

Objectives and competences

Students learn some tools of mathematical analysis that are important for applications in physics.

Intended learning outcomes

Knowledge and understanding:
We expect that students know important definitions and theorems, understand (and ideally be able to replicate) at least the easier proofs, and be able to apply this knowledge , e.g. in mathematical physics

Application:
The material of this course is indispensable for Mechanics, Mathematical physics and other courses in the program.

Reflection:
Students master some advanced topics in Mathematical Analysis and are able to apply them in physics.

Transferable skills:
Students learn to understand the usefulness of the abstract approach, are able to connect the acquired knowledge with what they already mastered. They also learn to use other written sources and the internet. They are able to identify and solve problems, hand in homework on time, and memorize the important topics.

Learning and teaching methods

Lectures, tutorials, homework (optional).

Assessment

Exercise-based exam / 2 midterm exams instead of written exam, written exam, homework optional).
Oral exam or theoretical test
grading: 5 (fail), 6-10 (pass) (according to the Statute of UL)
