WebMar 1, 2024 · An abelian extension of Hom-Lie algebras ( E) is an exact sequence of Hom-Lie algebras where ( M, α M) is an abelian Hom-Lie algebra, i and π are homomorphisms of Hom-Lie algebras and σ is a Hom-linear section of π. Remark 5.1. We might find the case when a surjective homomorphism of Hom-vector spaces does not have a section, as we … In mathematics, an algebraic extension is a field extension L/K such that every element of the larger field L is algebraic over the smaller field K; that is, if every element of L is a root of a non-zero polynomial with coefficients in K . A field extension that is not algebraic, is said to be transcendental, and … See more All transcendental extensions are of infinite degree.
