General Competencies

Learning advanced complex calculus and it’s use in various applications: conformal mappings, integral transforms, orthogonal polynomials and special functions.

Learning Outcomes

  1. operate with elementary functions in complex domain
  2. define and examine analytic property of functions
  3. apply the technique of conformal mappings in analyze of simple models
  4. use the technique of power series expansion in the calculus with elementary functions
  5. classify zeroes and singular points of analytic functions
  6. apply the technique of residuum, especially in the inverse integral transformation
  7. use the properties of gamma and beta function in various situations

Forms of Teaching

Lectures

Lectures are organized through two cycles. The first cycle consists of 7 weeks of classes and mid-term exam, a second cycle of 6 weeks of classes and final exam. Classes are conducted through a total of 15 weeks with a weekly load of 3 hours.

Exams

Mid-term exam in the 8th week of classes and final exam in the 15th week of classes.

Consultations

Consultations are held one hour weekly according to arrangement with students.

Grading Method

Continuous Assessment Exam
Type Threshold Percent of Grade Comment: Percent of Grade
Quizzes 0 % 20 % 0 % 20 %
Mid Term Exam: Written 0 % 40 % 0 %
Final Exam: Written 0 % 40 %
Exam: Written 0 % 80 %
Comment:

If student hasn't attended quizzes or wants to improve obtained results, he can take a written exam for 100% of grade.
