Proofs are given of the facts that any finite generalized hexagonal of order (2, t) is isomorphic to the classical generalized hexagon associated with the group G2(2) or to its dual if t = 2 and that it is isomorph to the group 3D4(2).Expand

For vector spaces of dimension at most 7 over fields of cohomo-ogical dimension at most 1 (including algebraically closed fields and inite fields) all trilinear alternating forms and their isotropy… Expand

This report summarizes the findings of a long and meticulous journey of data gathering and analysis to quantify the health losses from road deaths and injuries worldwide, as part of the path-finding… Expand

In this article the quaternionic reflection groups are classified. Such a group is defined so as to generalize the notion of reflection groups appearing in [4, 171, i.e., it is a group of linear… Expand

Pour j ≤ 4, on obtient pour tous les groupes exceptionnels une decomposition uniforme de la puissance tensorielle j-ieme de la representation adjointe, en accord avec les conjectures de Deligne [1].

The diagram algebra introduced by Brauer that describes the centralizer algebra of the n-fold tensor product of the natural representation of an orthogonal Lie group has a presentation by generators… Expand

Abstract For each n ≥ 2 , we define an algebra satisfying many properties that one might expect to hold for a Brauer algebra of type C n . The monomials of this algebra correspond to scalar multiples… Expand
