Abstract

We will introduce an algebraic structure called quandle. Its axiomatization comes from knot theory. Quandles can be seen as an abstraction from groups since many important examples arise as conjugation invariant subsets of groups. Quandles can be used, for example, to construct invariant of knots. In many situations we are faced with the following questions: determine the general structure of finite quandles, compute their second and third cohomology groups in particular. The talk will contain enough examples and calculations.
