= Wirtinger presentation
{wiki=Wirtinger_presentation}
The Wirtinger presentation is a method used in algebraic topology, particularly in the study of the fundamental group of a braid or a link in three-dimensional space. It was introduced by Wilhelm Wirtinger in the early 20th century. The Wirtinger presentation gives a way to describe the fundamental group of a knot or link by associating it with a specific set of generators and a set of relations derived from a diagram of the knot or link.
