Let f: XY and g: XY be two continuous maps between topological spaces X and Y. These maps are called homotopic if there exists a family φ t , for 0 ≤ t ≤ 1, of continuous maps
$${\varphi _t}:X \to Y$$
continuous with respect to t and xX simultaneously, and satisfying φ 0 = f, φ 1 = g. In words, two maps are homotopic if we can go from one to the other by means of a continuous deformation with parameter t ∈ [0, 1]. The family of maps φ t is called a homotopy between X and Y; it can also be regarded as a continuous map Φ :X × [0,1] → Y.
