Definition

A theorem describing how suspension stabilizes homotopy groups: for a sufficiently connected space X, the suspension homomorphism π_k(X) → π_{k+1}(ΣX) is an isomorphism in a range determined by the connectivity of X and is surjective slightly beyond that range, which leads to stable homotopy groups after iterated suspension.
