In the theory of C*-algebras, the Weyl groups were defined for the Cuntz
algebras and graph algebras by Cuntz and Conti et.al respectively. In this
paper, we introduce and investigate the Weyl groups of groupoid C*-algebras as
a natural generalization of the existing Weyl groups. Then we analyse several
groups of automorphisms on groupoid C*-algebras. Finally, we apply our results
to Cuntz algebras, graph algebras and C*-algebras associated with
Deaconu-Renault systems.
