Parapolar spaces with the “haircut” axiom

Ernest E. Shult

Vol. 15 (2017), No. 1, 265–286

In this paper, a generalization of a well-known result of Cohen and Cooperstein on strong parapolar spaces of symplectic rank at least three, with only finite-dimensional singular subspaces, is presented. In contrast with the aforementioned theorem, we do not assume that symplecta posses a uniform symplectic rank, we drop the assumption that the considered spaces are strong parapolar spaces, and we replace axiom (CC) by the much more general “haircut axiom."
