Homotopy-equivalent not implies homeomorphic for compact connected orientable 3-manifolds
Statement
It is possible to find two Compact connected orientable manifold (?)s and , both of dimension 3, such that and are both Homotopy-equivalent spaces (?) but are not Homeomorphic spaces (?).
Proof
Further information: three-dimensional lens space
Consider the three-dimensional lens spaces and . These are homotopy-equivalent but not homeomorphic.
