Students get acquainted with elementary functions in complex domain. They learn to look for their limits and to investigate their continuity. They are introduced to the derivative of a function of a complex variable and to Cauchy-Riemann conditions. A next topic is the integral of a function of a complex variable, Cauchy´s integral theorem and Cauchy's integral formula. As an application of residues, some integrals are computed with aid of the residue theorem. By means of linear, bilinear, power, exponential, and logarithmic functions, participants of the course will learn to map regions in Gaussian plane bijectively and conformally.

Differential and integral calculus.

Not applicable.

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

The course is finished by an oral examination. The examiner verifies the knowledge of definitions, theorems, and algorithms and the ability of their use in concrete applications.

The course aims to acquaint the students with the theory of functions of a complex variable. The explanation points via some indispensable concepts to the study of holomorphic functions. A next important notion is the integral of a function of a complex variable including the solution of the problem of independence of the path. Holomorphic functions can be developed, depending on the type of region, into Taylor series or, more generally, into Laurent series. Then, the classification of isolated singularities and residues with the residue theorem follow. The topic of conformal mapping gives a geometric application of holomorphic functions. The final part of the subject studies entire and meromorphic functions. As an application, a part concerning Hurwitz polynomials is attached.

Attendance at lectures is recommended. The lessons are planned on the basis of a weekly schedule. It is possible to study individually according to the recommended literature with the use of consultations.
