On $d$-dimensional dual hyperovals in $\mathsf{PG}(2d,2)$

DOI: 10.2140/iig.2008.8.137

We show that d-dimensional dual hyperovals in PG(2d,2) constructed from a regular nearfield of characteristic 2 are not isomorphic to Yoshiara’s d-dimensional dual hyperovals in PG(2d,2) constructed by Yoshiara. Thus we show that, in Cooperstein–Thas’s family, there exist non-isomorphic dual hyperovals.
