The twisted cubic in PG(3,q) and translation spreads in H(q)

Autor: G. Bonoli, Olga Polverino

Publikováno v: Discrete Mathematics. 296:129-142

Using the connection between translation spreads of the classical generalized hexagon H(q) and the twisted cubic of PG(3,q), established in [European J. Combin. 23 (2002) 367-376], we prove that if q^n=1(mod3), q odd, q>=4n^2-8n+2 and n>2, then H(q^n

A characterization of Grassmann and attenuated spaces as (0,α)-geometries

Autor: G. Bonoli, N. Melone

Publikováno v: European Journal of Combinatorics. 24(5):489-498

In this paper we introduce and study amply regular (0,α)-geometries satisfying the dual of Veblen–Young’s axiom, in order to give a common characterization of Grassmann and attenuated spaces.

In the energy region 10 - 100 TeV both the c.r. composition from direct measurements and the cross section for high energy secondary production in the very forward region for p-air interactions are rather uncertain. Contemporaneous measurements of th
