چکیده
A bstract The IKKT matrix model yields an emergent space-time. We further develop these ideas and give a proposal for metric. Based on previous numerical studies of this model, we provide evidence that the space-time is continuous infinite in extent, both space time, metric spatially flat. time evolution describes transition from string-theoretic phase to which SO(9) symmetry spontaneously broken SO(6) × SO(3), with three dimensions expanding, becoming classical at later times evolving like radiation-dominated universe, remaining six stabilized string scale. speculate how analysis can be extended yield early universe cosmology which, addition above-mentioned properties, also leads roughly scale-invariant spectrum cosmological fluctuations gravitational waves.

Fixed point theory in generalized orthogonal metric space
In this paper, among the other things, we prove the existence and uniqueness theorem of fixed point for mappings on a generalized orthogonal metric space. As a consequence of this, we obtain the existence and uniqueness of fixed point of Cauchy problem for the first order differential equation.
متن کاملFixed Point Theory in $varepsilon$-connected Orthogonal Metric Space
The existence of fixed point in orthogonal metric spaces has been initiated by Eshaghi and et. al [7]. In this paper, we prove existence and uniqueness theorem of fixed point for mappings on $varepsilon$-connected orthogonal metric space. As a consequence of this, we obtain the existence and uniqueness of fixed point for analytic function of one complex variable. The paper concludes with some i...
متن کاملMatrix Models , Emergent Gravity , and Gauge Theory
Matrix models of Yang-Mills type induce an effective gravity theory on 4-dimensional branes, which are considered as models for dynamical space-time. We review recent progress in the understanding of this emergent gravity. The metric is not fundamental but arises effectively in the semi-classical limit, along with nonabelian gauge fields. This leads to a mechanism for protecting certain geometr...
متن کاملMetric on a Statistical Space - Time
We introduce a concept of distance for a space-time where the notion of point is replaced by the notion of physical states e.g. probability distributions. We apply ideas of information theory and compute the Fisher information matrix on such a space-time. This matrix is the metric on that manifold. We apply these ideas to a simple model and show that the Lorentzian metric can be obtained if we ...
