摘要：

Let ACG(2 & nu;,Fq) $ACG(2\nu ,{{\mathbb{F}}}_{q})$ be the 2 & nu; $2\nu $-dimensional classical affine space with parameter e $e$ over a q $q$-element finite field Fq ${{\mathbb{F}}}_{q}$, and O & nu; ${{\mathscr{O}}}_{\nu }$ be the set of all maximal totally isotropic flats in ACG(2 & nu;,Fq) $ACG(2\nu ,{{\mathbb{F}}}_{q})$. In this paper, we discuss Cameron-Liebler sets in O & nu; ${{\mathscr{O}}}_{\nu }$, obtain several equivalent definitions and present some classification results.
