Hypertopes with prescribed diagram symmetries

Dimitri Leemans, Pablo Spiga, Philippe Tranchida

Let $G$ be a finite connected simple graph with at least two vertices. We construct a finite regular hypertope $Γ$ whose diagram is the graph $G$ with every edg…

Coset geometries acting on their elements: The $j$ -diagonals twisting

Claudio Alexandre Piedade, Philippe Tranchida

Let $β$ be a coset incidence system and fix a type $j$ . We use the orbits of the group of $β$ on pairs of distinct $j$ -elements to define a Coxeter graph. The action on the $j$ -ele…

The geometry of wreath and semi-direct products

Claudio Alexandre Piedade, Philippe Tranchida

Coset geometries are incidence geometries constructed from a group $G$ and a system of subgroups $(G_{i})_{i \in I}$ of subgroups of $G$ . For any algebraic group operation, it is the…
