Modular Invariants of a Vector and a Covector: a proof of a conjecture of Bonnafé and Kemper

Yin Chen, David L. Wehlau

Consider a finite dimensional vector space $V$ over a finite field ${\mathbb{F}}_q$. We give a minimal generating set for the ring of invariants $\mathbb{F}_q[V \oplus V^*]^{\text{GL…
