Zeeman’s conjecture

Zeeman’s conjecture

Alexander Kupers – GJM, Volume 6, Issue 1 (2021), 35-42.

Zeeman’s conjecture says that for every contractible 2-polyhedron K the product K \times I is collapsible. In this short survey, we discuss several examples and partial results, and explain that Zeeman’s conjecture for restricted classes of K is equivalent to the Poincaré conjecture and Andrews–Curtis conjecture with stabilisations.
