Title: Automorphisms of tiled orders
Author: Haefner, Jeremy; Pappacena, Christopher
Abstract: Let Λ be a tiled R-order. We give a description of AutR(Λ) as the semidirect product of Inn(Λ) and a certain subgroup of Aut(Q(Λ)), where Q(Λ) is the link graph of Λ. Additionally, we give criteria for determining when an element of Aut(Q(Λ)) belongs to this subgroup in terms of the exponent matrix for Λ. © 2002 Elsevier Science Inc. All rights reserved.
