A cross-intersecting Erd˝ os-Ko-Rado set of generators of a finite classical polar space is a pair (Y, Z) of sets of generators such that all y ∈ Y and z ∈ Z intersect in at least a point. We provide upper bounds on |Y | · |Z| and classify the cross-intersecting Erd˝ os-Ko-Rado sets of maximum size with respect to |Y | · |Z| for all polar spaces except some(More)
