Abstract: | In this paper, we first introduce new objects called “translation generalized ovals” and “translation generalized ovoids”,
and make a thorough study of these objects. We then obtain numerous new characterizations of the
of Tits and the classical generalized quadrangle
in even characteristic, including the complete classification of 2-transitive generalized ovals for the even case. Next,
we prove a new strong characterization theorem for the
of Tits. As a corollary, we obtain a purely geometric proof of a theorem of Johnson on semifield flocks.
