## Contents

• Complex differentiability, Cauchy-Riemann differential equations,
• Fundamentals of curve theory (curve length, curvature, number of turns) and curve integrals.
• Cauchy integral theorems and corollaries
• Isolated singularities, elementary holomorphic functions, meromorphic functions, Laurent series, residue theorem with applications,
• submanifolds of R^n (this topic can be treated by the lecturer alternatively in Analysis II)
• classical vector analysis (gradient, divergence, rotation), differential forms,
• integration on submanifolds, classical integral theorems (Stokes, Gauss, Ostrogradski ...), applications.

## Qualification Goals

Students will be able to,

• use complex-analytic methods to solve problems in real analysis,
• deal with complex-differentiable functions used in complex and algebraic geometry,
• apply integral theorems as a tool for describing various phenomena in mathematical physics (field theory, fluid mechanics, etc.),
• to reflect knowledge from the basic module Analysis and to consider it in connection with algebra, geometry and topology,
• to proceed according to mathematical working methods (developing mathematical intuition and its formal justification, training the ability to abstract),
• can speak freely about scientific content, both in front of an audience and in a discussion.

## Prerequisites

None. The competences taught in the following modules are recommended: either Foundations of Mathematics and Linear Algebra I and Linear Algebra II or Basic Linear Algebra, either Analysis I and Analysis II or Basic Real Analysis.
