Real and Complex Analysis - course description

Aim of the course

The aim is to improve the acquaitance of a student of deeper facts in real analysis and give him opportunity to gain the standard knowledge in the theory of complex functions in single variable.

Assignment conditions

1. Examination of the students’ preparation and their activity during exercises.
2. Tests, of different level of difficulty, permitting to verify the level of student commanding of the particular effects of education.
3. Exam (written and oral) checks the understanding of the basic notions, knowledge of the important examples and the proofs of some chosen theorems.
Passing the exam: the weighted mean of notes of exercises (40%) and the exam (60%).
A positive note of the exercises is the necessary condition to be admitted to the exam. A positive note of the exam attests the subject.
