## Abstract:

We consider vertices, a notion originating in local representation theory of finite groups, for the category $\mathcal {O}$ of a rational Cherednik algebra and prove the analogue of the Dipper-Du Conjecture for Hecke algebras of symmetric groups in that setting. As a corollary we obtain a new proof of the Dipper-Du Conjecture over $\mathbb {C}$.## References
