{wiki=U-invariant}
In mathematics, particularly in the context of algebra, "U-invariant" typically refers to a property of certain algebraic structures, often in relation to modules or representations over a ring or algebra. In the context of group representation theory, a subspace \\( W \\) of a vector space \\( V \\) is said to be U-invariant if it is invariant under the action of the group (or the algebra) associated with \\( V \\).
