Discrete Mathematics seminar - Philippe Tranchida

Time Thursday 8 June, 2023 at 15:15 - 16:15
Place MIT.B.372

Abstract: We introduce the notion of moving absolute geometry of a geometry with triality and show that certain cases the moving absolute geometry of the classical 7-dimensional quadric also gives interesting flag-transitive geometries. We also classify the classical absolute geometries for geometries with trialities but no dualities coming from maps (graphs embeddings on surfaces) of Class III with automorphism group L_2(q_3), where q is a power of a prime. This is joint work with Dimitri Leemans and Klara Stokes.

Event type: Seminar
