The organizers of the Algebraic Graph Theory International Webinar would like to invite you to join us and other colleagues on March 2, 2021, at 7pm Central European Time, for the next presentation delivered by Antonio Montero.
He will speak on Highly symmetric polytopes with prescribed local combinatorics
Convex polyhedra and tilings of the Euclidean or hyperbolic plane can be thought of as a family of polygons glued together along their edges. This idea extends to higher dimensions: a 4-dimensional cube can be thought of as a family of 3-dimensional cubes glued together along their 2-dimensional faces. This way of thinking of polytopes gives rise to some natural questions: given a n-dimensional polytope K, can we build a (n+1)-dimensional polytope P such that all the facets (maximal proper faces of P) are isomorphic to K? how many of such P can we build? Usually the geometry plays an important role in these questions. In the talk we will explore variants of this question in the context of abstract polytopes, where the geometry is less relevant. In particular, we are interested in the situation where prescribed symmetry conditions are imposed on P.
