Approximation by group invariant subspaces
(Gauthier-Villars/Editions Elsevier, 2020-10)
In this article we study the structure of Γ-invariant spaces of L2(S). Here S is a second countable LCA group. The invariance is with respect to the action of Γ, a non commutative group in the form of a semidirect product ...
The structure of group preserving operators
(Springer, 2021-04-27)
In this paper, we prove the existence of a particular diagonalization for normal bounded operators defined on subspaces of 2() where is a second countable LCA group. The subspaces where the operators act are invariant ...
Castelnuovo Mumford regularity with respect to multigraded ideals
(Academic Press Inc Elsevier Science, 2017-03)
In this article we extend a previous definition of Castelnuovo–Mumford regularity for modules over an algebra graded by a finitely generated abelian group. Our notion of regularity is based on Maclagan and Smith's definition, ...
Electron dynamics in complex environments with real-time time dependent density functional theory in a QM-MM framework
(American Institute of Physics, 2014-04)
This article presents a time dependent density functional theory (TDDFT) implementation to propagate the Kohn-Sham equations in real time, including the effects of a molecular environment through a Quantum-Mechanics ...
