Knot Theory
In the context of knot theory, a relation refers to an equation that defines how certain generators of a knot group are interconnected or constrained. These relations arise from the crossings in a knot diagram and form the backbone of the Wirtinger presentation, allowing for the establishment of a formal structure within which knot groups can be studied. Relations help in determining the properties and classifications of knots based on their representations.
