Learning outcomes

To learn and get excited on simply formulated problems and results on sequences of elements, as well as to see connections of this topic to numerous areas of sciences, not only in mathematical sciences.


A word is a finite or infinite sequence of symbols (from a finite set). In this course we consider simple, as well as more advanced, combinatorial problems of words. For example, when two words commute, or how long words exist without containing a repetition of a certain type (like a square). Also some more algebraic properties of words are considered, results have applications in many fields of discrete mathematics and theoretical computer science.
