Talk:End (graph theory)

The cops and robbers explanation is rather confusing, it should be re-stated more clearly. [ɯ:] (talk) 10:55, 29 August 2015 (UTC)

Incomplete and unclear definition of "ends" of a topological space

The section Relation to topological ends contains this explanation:

"If a topological space can be covered by a nested sequence of compact sets $\kappa _{0}\subset \kappa _{1}\subset \kappa _{2}\dots$, then an end of the space is a sequence of components $U_{0}\supset U_{1}\supset U_{2}\dots$ of the complements of the compact sets. This definition does not depend on the choice of the compact sets: the ends defined by one such choice may be placed in one-to-one correspondence with the ends defined by any other choice."

This definition of ends of topological spaces is both incomplete and unclear. 2601:200:C000:1A0:D028:9F22:534E:3701 (talk) 21:04, 13 September 2021 (UTC)
