Tutte homotopy theorem

In mathematics, the Tutte homotopy theorem, introduced by Tutte (), generalises the concept of "path" from graphs to matroids, and states roughly that closed paths can be written as compositions of elementary closed paths, so that in some sense they are homotopic to the trivial closed path.
