Random Triangular Groupsore interesting, we show that there exist constants .′, .′ > 0 such that if ., then a.a.s. a random group . is neither free, nor has Kazhdan’s property (T). We prove the above statements using random graphs and random hypergraphs.

Generalized Involution Models of Projective Reflection Groupstside a finite list of exceptional cases. Building on prior work, this allows us to prove that .(., ., 1, .) has a generalized involution model if and only if .. We also classify which groups .(., ., ., .) have generalized involution models when . = 2, or . is odd, or . is odd.

On a Conjecture of Holtz and Ron Concerning Interpolation, Box Splines, and Zonotopescit solution to this interpolation problem in terms of truncations of the Todd operator. As a corollary we obtain a slight generalisation of the Khovanskii-Pukhlikov formula that relates the volume and the number of lattice points in a smooth lattice polytope.

Norberto Patrignani,Diane Whitehouseations holding for matroids (e.g., duality), and we explicitly describe the structure of the matroids over .. Furthermore, we compute the Tutte-Grothendieck ring of matroids over .. We also show that the Tutte quasi-polynomial of a matroid over . can be obtained as an evaluation of the class of the matroid in the Tutte-Grothendieck ring.
