New invariants for incidence structures

Speaker: Vladimir Tonchev Affiliation: Michigan Technological University Room: Mathematics and Computer Building (MC) 5158

Abstract:

New isomorphism invariants for incidence structures based on a connection between trace codes and Galois geometry are discussed. Using these invariants, a new Hamada type characterization of the classical finite geometry designs is proved.
