Constructing zero divisors in the higher dimensional Cayley-Dickson algebras
Guillermo Moreno
In this paper we give new methods to construct zero divisors in A_n =R^(2^n) the Cayley_Dickson algebras over the real numbers, for n larger than 4, and we also relate the set of z…
Monomorphisms between Cayley-Dickson Algebras
Guillermo Moreno
In this paper we study the algebra monomorphisms from A_m =R^(2^m) into A_n=R^(2^n) for 0<m<n where the A_k 's are the Cayley- Dickson algebras over the real numbers. We show that…
Constraining non-standard interactions in nu_e e or bar{nu}_e e scattering
J. Barranco, O. G. Miranda, C. A. Moura +1
We present a new analysis of non-universal and flavor changing non-standard neutrino interactions (NSI) in ν_e e or \barν_e e scattering. Our global analysis of these process inclu…
An Alternative Interpretation for the Moduli Fields of the Cosmology Associated to Type IIB Supergravity with Fluxes
Tonatiuh Matos, Jose-Ruben Luevano, Hugo Garcia-Compean
We start with a particular cosmological model derived from type IIB supergravity theory with fluxes, where usually the dilaton is interpreted as a Quintessence field. Instead of th…
The damped harmonic oscillator in deformation quantization
Giuseppe Dito, Francisco Turrubiates
We propose a new approach to the quantization of the damped harmonic oscillator in the framework of deformation quantization. The quantization is performed in the Schrödinger pictu…
On bounds for some graph invariants
Isidoro Gitler, Carlos E. Valencia
Let be a graph without isolated vertices and let be its stability number and its covering number. The {\it -cover} number of a graph, denoted by …
