Instructor: Dr. Sándor Dobos;

Text:  Hungarian Problem Book III
and printed handouts

Prerequisite: None, but general mathematical experience needed.

Course description: The course provides an introduction to the most important problem-solving techniques typically encountered in undergraduate mathematics. Problems and proofs from different topics of mathematics will help us to understand what makes a proof complete and correct. Some games make the course colorful, we analyse how to play, how to build strategies.
The text is the collection of problems of Kürschák Competition which is rightly recognized as the forerunner of all national and international olympiads.
