Alternating forms and transitive locally grid geometries
Let V be a vector space over K. For each nonnegative integer k let Pk(V ) be the set of k-subspaces of V . For positive d (≤ dimV ), let Ld(V ) be the set of pairs (U,W ) with U ∈ Pd−1(V ), W ∈ Pd+1(V ), and U ≤ W . We also set B− d (V ) = Pd−1(V ), B + d (V ) = Pd+1(V ), and Bd(V ) = B − d (V ) ∪ B + d (V ). In the case V = K and d = 2, we can view P2(V ) and L2(V ) as the points and lines of ...
متن کاملAlternating Normal Forms for Braids and Locally Garside Monoids
We describe new types of normal forms for braid monoids, Artin– Tits monoids, and, more generally, all monoids in which divisibility has some convenient lattice properties (“locally Garside monoids”). We show that, in the case of braids, one of these normal forms turns out to coincide with the normal form introduced by Burckel and deduce that the latter can be computed easily. This approach lea...
متن کاملOn Flag-transitive Anomalous C 3 -geometries
A nite C 3-geometry is called anomalous if it is neither a building nor the A 7-geometry. It is conjectured that no ag-transitive thick anomalous C 3-geometry exists. For a ag-transitive thick anomalous C 3-geometry, we prove that its 2-order y is odd and that its full automorphism group is non-solvable. As a corollary, there are no ag-transitive circular extensions of duals of anomalous C 3-ge...
متن کاملOn Flat Flag-Transitive c.c∗-Geometries
We study flat flag-transitive c.c∗-geometries. We prove that, apart from one exception related to Sym(6), all these geometries are gluings in the meaning of [6]. They are obtained by gluing two copies of an affine space over GF(2). There are several ways of gluing two copies of the n-dimensional affine space over GF(2). In one way, which deserves to be called the canonical one, we get a geometr...
متن کاملLocally s-distance transitive graphs
We give a unified approach to analysing, for each positive integer s, a class of finite connected graphs that contains all the distance transitive graphs as well as the locally s-arc transitive graphs of diameter at least s. A graph is in the class if it is connected and if, for each vertex v, the subgroup of automorphisms fixing v acts transitively on the set of vertices at distance i from v, ...
