Homotopy logo #21000 In topology, two continuous functions from one topological space to another are called homotopic (Greek ὁμός (homós) = same, similar, and τόπος (tópos) = place) if one can be `continuously deformed` into the other, such a deformation being called a homotopy between the two functions. A notable use of homotopy is the definition of hom.....

homotopy

homotopy logo #21160A continuous transformation from one path in a topological space to another, or, more generally, of one function to another. Paths connected by a homotopy are called homotopic and are said to be in the same homotopy class. Properties left unchanged by such homotopies are known as homotopy invariants...
