Web6 Mar 2024 · A split monomorphism is a homomorphism that has a left inverse and thus it is itself a right inverse of that other homomorphism. That is, a homomorphism f: A → B is a split monomorphism if there exists a homomorphism g: B → A such that g ∘ f = Id A. A split monomorphism is always a monomorphism, for both meanings of monomorphism. WebThe splitting map is a homomorphism of groups, so it must carry identity to identity. Hence, the splitting map is completely determined by where it sends the only non-identity element, − 1. The image of the splitting, s ( { ± 1 }) ⊆ S n is a little isomorphic copy of Z 2 inside S n. …
