We consider vertices, a notion originating in local representation theory of finite groups, for the category 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 C. [ABSTRACT FROM AUTHOR]
