چکیده

In this paper we consider some finite generalized polygons, defined over a field with characteristic 2, that admit an embedding in a projective or affine space over a field with characteristic unequal to 2. In particular, we classify the (lax) embeddings of the unique generalized quadrangle H(3, 4) of order (4, 2). We also classify all (lax) embeddings of both the split Cayley hexagon H(2) and its dual H(2)dual in 13dimensional projective space PG(13, K), for any skew field K. We apply our results to classify the homogeneous embeddings of these small generalized hexagons, and to classify all homogeneous lax embeddings in real spaces of them. Also, we classify all homogeneous embeddings of generalized quadrangles of order (2, 2), (4, 2) and (2, 4). Mathematics Subject Classification 2000: 51E12.

Automorphisms and characterizations of finite generalized quadrangles

Our paper surveys some new developments in the theory of automorphisms and characterizations of finite generalized quadrangles. It is the purpose to mention important new results which did not appear in the following standard works (or surveys) on the subject: Collineations of finite generalized quadrangles (S. E. Payne, 1983), Finite Generalized Quadrangles (S. E. Payne and J. A. Thas, 1984), ...

Some Constructions of Small Generalized Polygons

We present several new constructions for small generalized polygons using small projective planes together with a conic or a unital, using other small polygons, and using certain graphs such as the Coxeter graph and the Pappus graph. We also give a new construction of the tilde geometry using the Petersen graph. 2001 Academic Press

Epimorphisms of Generalized Polygons Part 1: Geometrical Characterizations

A generalized polygon is a thick incidence geometry of rank 2 such that the girth of the incidence graph is twice the diameter of the incidence graph. These geometries are introduced by Tits [17] for group-theoretical purposes, but became an interesting research object in their own right. For an overview of the geometric study, see [19]. Obviously, the notion of morphism is an important one whe...

Isometric embeddings between the near polygons H n and G n

Let n ∈ N \ {0, 1, 2}. We prove that there exists up to equivalence one and up to isomorphism (n + 1)(2n + 1) isometric embeddings of the near 2n-gon Hn into the near 2n-gon Gn.

An Exploration of Embeddings for Generalized Phrases

Deep learning embeddings have been successfully used for many natural language processing problems. Embeddings are mostly computed for word forms although lots of recent papers have extended this to other linguistic units like morphemes and word sequences. In this paper, we define the concept of generalized phrase that includes conventional linguistic phrases as well as skip-bigrams. We compute...
