Low-Twist Matrix Covariants of Exterior Powers: Vanishing and Modular Phenomena

We study GL(V)-equivariant morphisms between the polynomial representations Symᵈ(ΛʳV) and End(V) ⊗ det(V) to the ℓ-th tensor power. Scalar matrices impose the necessary condition rd = nℓ, which organizes the first two determinant twists studied here. In characteristic zero we det...
