Spectral properties of 4-dimensional compact flat manifolds
Roberto Miatello, Ricardo Podesta
We study the spectral properties of a large class of compact flat Riemannian manifolds of dimension 4, namely, those whose corresponding Bieberbach groups have the canonical lattic…
On Braided Groupoids
C. Maldonado, J. M. Mombelli
We study and give examples of braided groupoids, and, a fortiori, non-degenerate solutions of the quiver-theoretical braid equation.
Environmentally induced Quantum Dynamical Phase Transition in the spin swapping operation
Gonzalo Agustin Alvarez, Ernesto Pablo Danieli, Patricia Rebeca Levstein +1
Quantum Information Processing relies on coherent quantum dynamics for a precise control of its basic operations. A swapping gate in a two-spin system exchanges the degenerate stat…
A canonical compatible metric for geometric structures on nilmanifolds
Jorge Lauret
Let (N,g) be a nilpotent Lie group endowed with an invariant geometric structure (cf. symplectic, complex, hypercomplex or any of their `almost' versions). We define a left invaria…
Regular Motions in Extra-Solar Planetary Systems
S. Ferraz-Mello, T. A. Michtchenko, C. Beauge
This paper is a review of the dynamics of a system of planets. It includes the study of averaged equations in both non-resonant and resonant systems and shows the great deal of sit…
