Abelian Gauge Fluxes and Local Models in F-TheoryNov 03 2009Feb 28 2010We analyze the Abelian gauge fluxes in local F-theory models with G_S=SU(6) and SO(10). For the case of G_S=SO(10), there is a no-go theorem which states that for an exotic-free spectrum, there are no solutions for U(1)^2 gauge fluxes. We explicitly construct ... More

Birkhoff spectra for one-dimensional maps with some hyperbolicityMar 11 2008We study the multifractal analysis for smooth dynamical systems in dimension one. It is characterized the Hausdorff dimension of the level set obtained from the Birkhoff averages of a continuous function by the local dimensions of hyperbolic measures ... More

The cosmic origin of supersymmetry and internal symmetryJan 31 2001Feb 06 2001The cosmic vacuum is the wavefunction of the eleven dimensional Planck supermembrane. The Planck wavefunction is the superposition of dimensions from eleven to four dimensional spacetime with decreasing energy and increasing size. The cosmic vacuum is ... More

The masses of elementary particles and hadronsMar 23 2000Jul 28 2001The masses of elementary particles and hadrons can be calculated from the periodic table of elementary particles. The periodic table is derived from dimensional hierarchy for the seven extra spatial dimensions. As a molecule is the composite of atoms ... More
