{wiki=Eilenberg–Ganea_theorem}
The Eilenberg–Ganea theorem is a fundamental result in algebraic topology, specifically in the theory of topological spaces and homotopy theory. Named after mathematicians Samuel Eilenberg and Tadeusz Ganea, the theorem concerns the relationship between the fundamental group of a space and its higher homotopy groups.
