Matrices in companion rings and their Smith forms, with applications to group theory and algebraic topology – Vanni Noferini (University of Essex and Aalto University)

Archivio 25 March 2019 10:00 - 11:00 Sala Seminari (Dip. Matematica).

In group theory, various properties of the abelianization of a cyclically presented group can be deduced by the Smith normal form of an integer circulant matrix. Motivated by this fact, we present a number of results on the Smith form of matrices…
