Universal entropy bound and discrete space-time
entropy bound discrete space-time
font style='font-size:12px;'>
2011/9/29
Starting from the universal entropy bounds suggested by Bekenstein and Susskind and applying them to the black-body radiation situation, we get a cut-off of space x ≥ lP with ≥ 0.1. We go further ...
Matrix Model for membrane and dynamics of D-Particles in a curved space-time geometry and presence of form fields
Matrix Model membrane dynamics D-Particles

2010/12/23
We study dynamics of a membrane and its matrix regularisation. We present the matrix regularisation for a membrane propagating in a curved space-time geometry in the presence of an arbitrary 3-form fi...

We will study the theory of scalar field in non-commutative curved space time (NCCST) with a percussionist who has been found by Mebaraki. In this paper, the motion equation of the scalar field will ...

We discuss alternatives to the usual quantization of relativistic particles which result in discrete spectra for position and time operators
Space-Time Compactification, Non-Singular Black Holes, Wormholes and Braneworlds via Lightlike Branes
Space-Time Compactification Non-Singular Black Holes Wormholes and Braneworlds Lightlike Branes

We describe a concise general scheme for constructing solutions of Einstein-Maxwell-Kalb-Ramond gravity-matter system in bulk space-time interacting selfconsistently with one or more (widely separated...
Instability of the planetary orbits for space-time dimensions higher than four
Instability planetary orbits space-time dimensions
font style='font-size:12px;'>
2010/12/20
It is shown that in a Minkowski space of total space-time dimension D = d + 1, the orbits of the planetary motion are stable only if the total dimension of space-time is D 4. The proof is performed ...
Symmetries of Self-Dual Yang-Mills Equations Dimensionally Reduced From (2,2) Space-time
Self-Dual Yang-Mills Equations Space-time
font style='font-size:12px;'>
2010/12/22
We construct infinite-dimensional symmetries of the two dimensional equation which results from the dimensional reduction of the self-duality condition in (2, 2) signature space-time. These are symme...
Nucleon form factors：the space-time connection
dispersion relations nucleon form factors pQCD
font style='font-size:12px;'>
2010/5/7
Analyticity of nucleon form factors allows to derive sum rules which, using space-like and time-like
data as input, can give unique information about behaviors in energy regions not experimentally ac...
de Sitter expansion with anisotropic fluid in Bianchi type-I space-time
Bianchi type-I de Sitter expansion cosmological constant anisotropic fluid
font style='font-size:12px;'>
2010/3/17
Some features of the Bianchi type-I universes in the presence of a fluid that wields an anisotropic equation of state (EoS) parameter are discussed in the context of general relativity. The models tha...
The Space-Time Critical Dimension of an Open Parabosonic String
Space-Time Critical Dimension Open Parabosonic String

2010/4/19
Using analytical properties of a 1-loop open parabosonic M-point transition amplitude, we show that the space-time critical dimension depends on the order of the paraquantization.
