components_link

Link components represent distinct closed loops in a link diagram.

A trefoil knot has one component, while the Hopf link has two.

Functions

link_components_endpoints(k)	Return sets of endpoints belonging to the same link component.
number_of_link_components(k)	Return the number of link components in a planar diagram.

number_of_link_components(k)

Return the number of link components in a planar diagram.

For example, a trefoil knot has 1 component, while the Hopf link has 2 components.

Parameters:

k (PlanarDiagram)

Return type:

int

link_components_endpoints(k)

Return sets of endpoints belonging to the same link component.

Endpoints are grouped into the same component if they are connected through arcs or at nodes in the diagram.

Parameters:

k (PlanarDiagram)

Return type:

list[set]
