Objectives and competences

This is one of the three basic courses in which students learn to think geometrically. The basic goal is to understand the basic definitions and properties of algebraic curves.

Intended learning outcomes

Knowledge and understanding: Understanding the relation between the algebraic equations and the geometric objects. Ability of treating some geometric problems by means of tools, coming from the theory of polynomials. Knowledge and understanding of the fundamental concepts of the theory of algebraic curves and algebraic geometry.
Application: Algebraic description of objects, appearing in problems from other areas of mathematics and its applications. Application of algebro-geometric methods in the treatment of such problems.
Reflection: Ability of percieving mathematical object from different points of view. Development of the geometric approach to solving problems in applicative mathematics.
Transferable skills: Formulation of problems in suitable contexts, evaluation of developed tools in concrete examples. This course demands a firm knowledge of certain chapters from mathematical analysis and algebra. Therefore students learn how to use previously acquired knowledge in new situations. Students learn the use of study literature in foreign languages.
