All major tools in algebraic topology (homology, cohomology, and homotopy) all turn out to be invariant under homotopy equivalence.

Given two topological spaces X and Y, a homotopy equivalence between X and Y is a pair of continuous maps f : X → Y and g : Y → X, such that g ∘ f is homotopic to the identity map idX and f ∘ g is homotopic to idY. If such a pair exists, then X and Y are said to be homotopy equivalent, or of the same … Meer weergeven In topology, a branch of mathematics, two continuous functions from one topological space to another are called homotopic (from Ancient Greek: ὁμός homós "same, similar" and τόπος tópos "place") if one can be … Meer weergeven Formally, a homotopy between two continuous functions f and g from a topological space X to a topological space Y is defined to be a continuous function $${\displaystyle H:X\times [0,1]\to Y}$$ from the product of the space X with the unit interval [0, … Meer weergeven Lifting and extension properties If we have a homotopy H : X × [0,1] → Y and a cover p : Y → Y and we are given a map h0 : X → Y such that H0 = p ○ h0 (h0 is called a lift of h0), then we can lift all H to a map H : X × [0, 1] → Y such that p ○ H = H.
