In [[mathematics]], particularly the area of [[topology]], a '''simple-homotopy equivalence''' is a refinement of the concept of [[homotopy equivalence]]. Two [[CW-complex]]es are simple-homotopy equivalent if they are related by a sequence of [[collapse (topology)|collapses]] and expansions (inverses of collapses), and a homotopy equivalence is a simple homotopy equivalence if it is homotopic to such a map.

The obstruction to a homotopy equivalence being a simple homotopy equivalence is the [[Whitehead torsion]], <math>\tau(f).</math>
