An equivalent form of the conjecture involves a coarser form of equivalence than homeomorphism called homotopy equivalence : if a 3-manifold is homotopy equivalent to the 3-sphere, then it is necessarily homeomorphic to it. Source: Internet
An introductory exercise is to classify the uppercase letters of the English alphabet according to homeomorphism and homotopy equivalence. Source: Internet
An embedding, or a smooth embedding, is defined to be an injective immersion which is an embedding in the topological sense mentioned above (i.e. homeomorphism onto its image). Source: Internet
A self-homeomorphism is a homeomorphism of a topological space and itself. Source: Internet
Homotopy equivalence is a rougher relationship than homeomorphism; a homotopy equivalence class can contain several homeomorphism classes. Source: Internet
