Classifying involutions of Azumaya algebras on schemes

February 6, 2023

MATH 126

An involution on a ring A is a self-map of order 2 that is additive and reverses the order of multiplication. I will motivate the work by explaining the classification of involutions of central simple algebras over fields. In this context, the involution acts either trivially ... Read more
