LMA MSW solution of the solar neutrino problem and first KamLAND results
P. C. de Holanda, A. Yu. Smirnov
The first KamLAND results are in a very good agreement with the predictions made on the basis of the solar neutrino data and the LMA realization of the MSW mechanism. We perform a…
Metric Tensor Vs. Metric Extensor
V. V. Fernández, A. M. Moya, Waldyr A. Rodrigues
In this paper we give a comparison between the formulation of the concept of metric for a real vector space of finite dimension in terms of \emph{tensors} and \emph{extensors}. A n…

This paper is an introduction to the theory of multivector functions of a real variable. The notions of limit, continuity and derivative for these objects are given. The theory of…
A Goppa-like bound on the trellis state complexity of algebraic geometric codes
Carlos Munuera, Fernando Torres
For a linear code $\cC$ of length and dimension , Wolf noticed that the trellis state complexity $s(\cC)$ of $\cC$ is upper bounded by $w(\cC):=\min(k,n-k)$. In this paper w…
Measurements of the Decay KL->e+e-mu+mu-
The KTeV Collaboration
The KTeV experiment at Fermilab has isolated a total of 132 events from the rare decay KL->e+e-mu+mu-, with an estimated background of 0.8 events. The branching ratio of this mode…
The Relation between Maxwell, Dirac and the Seiberg-Witten Equations
Waldyr A. Rodrigues
In this paper we discuss some unusual and unsuspected relations between Maxwell, Dirac and the Seiberg-Witten equations. First we investigatethe Maxwell-Dirac equivalence (MDE) of…
The Bundles of Algebraic and Dirac-Hestenes Spinor Fields
Ricardo A. Mosna, Waldyr A. Rodrigues
The main objective of this paper is to clarify the ontology of Dirac-Hestenes spinor fields (DHSF) and its relationship with sum of even multivector fields, on a general Riemann-Ca…
Algebraic and Dirac-Hestenes Spinors and Spinor Fields
Waldyr A. Rodrigues
Almost all presentations of Dirac theory in first or second quantization in Physics (and Mathematics) textbooks make use of covariant Dirac spinor fields. An exception is the prese…

Christine C. Dantas, Hugo V. Capelato, Andre L. B. Ribeiro +1
We present a new set of dissipationless N-body simulations aiming to better understand the pure dynamical aspects of the ``Fundamental Plane'' (FP) of elliptical galaxies. We have…
