The Globalization problem for inner automorphisms and Skolem-Noether theorems
(World Science, 2003-07)
We investigate the circumstances under which an inner automorphism of a ring
with local units can be built from “local” information. Specifically, we consider three
natural “inner” type properties for an automorphism of ...
Mind over matter: Transforming course management systems into effective learning environments
(EDUCAUSE, 2002-12)
Integrating best practices for "deeper learning" with the robust tools provided by course management systems creates an incredibly effective, engaging, and student-centered learning environment.
Automorphisms of tiled orders
(Elsevier, 2002)
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 ...
Strongly graded hereditary orders
(2001-08-28)
Let R be a Dedekind domain with global quotient field K. The
purpose of this note is to provide a characterization of when a strongly graded
R-order with semiprime 1-component is hereditary. This generalizes earlier
work ...
Hereditary crossed products
(American Mathmatical Society, 2000-03-27)
We characterize when a crossed product order over a maximal
order in a central simple algebra by a finite group is hereditary. We need only
concentrate on the cases when the group acts as inner automorphisms and
when ...
