Abstract: | A point X of a projective space Pn (over a commutative field of characteristic 2) is called an outer point of a quadric Qn–1 if and only if X is not a point of Qn–1 and the polar hyperplane X contains a maximal subspace of Qn–1; the points of PnQn–1 which are not outer points of Qn–1 are called inner points of Qn–1. This definition is motivated by special cases in classical projective geometry; it improves earlier definitions.
