Construction of perfect space-time codes
(2013-04-29)
In this work, we propose an innovative methodology to extend the construction of minimum and non-minimum delay perfect codes as a subset of cyclic division algebras over ℚ(ζ3), where the signal constellations are isomorphic ...
A canonical decomposition of the integral trace over cyclic number fields of a given discriminant
(UniandesDoctorado en MatemáticasFacultad de CienciasDepartamento de Matemáticas, 2019)
"En este trabajo se estudia extensiones cíclicas del cuerpo de los números racionales y su módulo traza integral subyacente siendo este totalmente determinado solamente por el discriminante del cuerpo de números." -- Tomado ...
Intransitivity and coexistence in four species cyclic games
(Elsevier, 2013-01)
Intransitivity is a property of connected, oriented graphs representing species interactions that may drive their coexistence even in the presence of competition, the standard example being the three species Rock-Paper-Scissors ...
Fields of two power conductor
(2013)
The goal of this work is find a description for fields of two power conductor. By the Kronecker-Weber theorem, these amounts to find the subfields of cyclotomic field $\mathbb{Q}(\xi_{2^r})$, where $\xi_{2^r}$ is a $2^r$-th ...

Cyclic electric field stress on bipolar resistive switching devices
(American Institute of Physics, 2013-12)
We have studied the effects of accumulating cyclic electrical pulses of increasing amplitude on the non-volatile resistance state of interfaces made by sputtering a metal (Au, Pt) on top of the surface of a cuprate ...
