In invariant theory, a branch of algebra, given a group G, a covariant is a G-equivariant polynomial map <math>V \to W</math> between linear representations V, W of G.[1] It is a generalization of a classical convariant,Шаблон:Clarify which is a homogeneous polynomial map from the space of binary m-forms to the space of binary p-forms (over the complex numbers) that is <math>SL_2(\mathbb{C})</math>-equivariant.[2]
