We adapt and refine the methods developed in [Abr96] and [DGM] in order to establish the sphericity of the Phan geometries defined in [BGHS07] (type Bn) and [GHS03] (type Cn), and their generalizations. As applications of this sphericity we determine the topological finiteness length of the unitary form of the group Sp 2n (F q2 [t, t]) (Theorem 7.1) and give the first published proof of the Pha...

In this paper we introduce the Bidimensional Sand Pile Model (BSPM), that is, a generalization of the Sand Pile Model (SPM) with the addition of a further dimension. The SPM and some related models have been studied in many different domains and they play an important role in the theory of discrete dynamical systems. They were considered in the context of integer lattices by Brylawski in 1973. ...

Geometric methods in the theory of Chevalley groups and their generalisations have made tremendous advances during the last few decades. Among the most noteworthy and influential of these advances are the systematic application of the concept of amalgams based on [49], [59], [117], the local-to-global approach [134], ingenious applications of combinatorial topology and geometric group theory (a...

The Password-authenticated key exchange (PAKE) protocols allow parties to share secret keys in an authentic manner based on an easily memorizable password. On the other hand, the protocol should resist all types of password guessing attacks, since the password is of low entropy. Recently Lu Cao proposed a simple three-party password based authenticated key exchange (S-3 PAKE) protocol and claim...

We prove that the complex of proper non-trivial non-degenerate subspaces of a finitedimensional vector space endowed with a non-degenerate sesquilinear form is homotopy equivalent to a wedge of spheres. Additionally, we show that the same is true for a slightly wider class of simplicial complexes, the so-called generalized Phan geometries of type An. These generalized Phan geometries occur as r...
