Invariants of automorphic lie algebras

open access: yes
Automorphic Lie Algebras arise in the context of reduction groups introduced in the late 1970s [35] in the field of integrable systems. They are subalgebras of Lie algebras over a ring of rational functions, denied by invariance under the action of a ...

Realizability of algebraic Galois extensions by strictly commutative ring spectra

open access: yes, 2007
We discuss some of the basic ideas of Galois theory for commutative S-algebras originally formulated by John Rognes. We restrict our attention to the case of finite Galois groups and to global Galois extensions.

Ideals and Maximal Commutative Subrings of Graded Rings [Elektronisk resurs]

open access: yes, 2009
This thesis is mainly concerned with the intersection between ideals and (maximal commutative) subrings of graded rings. The motivation for this investigation originates in the theory of C*-crossed product algebras associated to topological dynamical ...
