Stabilisation of Seven ( Toroidal ) Directions and Expansion of the remaining Three in an M theoretic Early Universe Model

چکیده

Our model consists of intersecting 2255 brane configuration in M theory, distributed uniformly in the common transverse space and assumed to describe early universe. Equations of state are those following from U duality symmetries and a few standard assumptions. In this model, three spatial directions expand, and seven directions stabilise to constant sizes which depend on certain imbalance among initial values. One naturally obtains M11 ≃ Ms ≃ M4 and gs ≃ 1 within a few orders of magnitude. Smaller numbers, for example Ms ≃ 10 −16 M4 , are also possible but require fine tuning.

A meshless discrete Galerkin method for solving the universe evolution differential equations based on the moving least squares approximation

In terms of observational data, there are some problems in the standard Big Bang cosmological model. Inflation era, early accelerated phase of the evolution of the universe, can successfully solve these problems. The inflation epoch can be explained by scalar inflaton field. The evolution of this field is presented by a non-linear differential equation. This equation is considered in FLRW model...

On independent domination numbers of grid and toroidal grid directed graphs

A subset $S$ of vertex set $V(D)$ is an {em indpendent dominating set} of $D$ if $S$ is both an independent and a dominating set of $D$. The {em indpendent domination number}, $i(D)$ is the cardinality of the smallest independent dominating set of $D$. In this paper we calculate the independent domination number of the { em cartesian product} of two {em directed paths} $P_m$ and $P_n$ for arbi...

A Game Theoretic Approach for Sustainable Power Systems Planning in Transition

Intensified industrialization in developing countries has recently resulted in huge electric power demand growth; however, electricity generation in these countries is still heavily reliant on inefficient and traditional non-renewable technologies. In this paper, we develop an integrated game-theoretic model for effective power systems planning thorough balancing between supply and demand for e...

Formation of Large Structures in the Acceleration Universe with a Hybrid Expansion Law

In the current paper, we have studied the effect of dark energy on for-mation where dark energy exists in the background. For this purpose, we used both WMAP9 and Planck data to study how the radius changes with redshift in these mod-els. We used different data sets to fix the cosmological parameters to obtain a solution for a spherical region under collapse. The mechanism of structure formation f...
