Titre / Title: Harvey-Wiman hypermaps
Abstract : We show that on a hypermap (a,s) of genus g>1, an automorphism y is either of order p(1+2g/(p-1)) if (p,1+2g/(p-1))=1, or o(y) ¾ 2pg/(p-1), where p is the smallest divisor of the order Aut(a,s). We also give bounds on the order Aut(a,s) depending on p..We define p-Harvey hypermaps as the ones admitting an automorphism of order p(1+2g/(p-1)) (type I) or 2pg/(p-1) (type II) and characterize "most of them " as p-elliptic hypermaps.
