چکیده

Considering space--time to be non-commutative, we study the evolution of universe employing approach Newtonian cosmology. Generalizing conservation energy and first law thermodynamics $\kappa$-deformed space--time, derive modified Friedmann equations, valid up order, in deformation parameter. Analyzing these deformed time scale factor cases radiation-dominated, matter-dominated, vacuum (energy)-dominated universes. We show that rate change all three situations is by non-commutativity this depends on sign parameter, indicating a possible explanation for observed Hubble tension. undertake investigation two different realizations non-commutative coordinates. In both cases, also argue existence bounce universe.

κ-deformed gauge theory and θ-deformed gravity

Noncommutative (deformed, quantum) spaces are deformations of the usual commutative space-time. They depend on parameters, such that for certain values of parameters they become the usual space-time. The symmetry acting on them is given in terms of a deformed quantum group symmetry. In this work we discuss two special examples, the θ-deformed space and the κ-deformed space. In the case of the θ...

Evolution of Information and Complexity in an Ever-Expanding Universe

Using the usual definitions of information and entropy in quantum gravity and statistical mechanics and the existing views about the relation between information and complexity, we examine the evolution of complexity in an ever expanding universe.

Κ-deformed Kinematics and Addition Law for Deformed Velocities * †

In κ-deformed relativistic framework we consider three different definitions of κ-deformed velocities and introduce corresponding addition laws. We show that one of the velocities has classical relativistic addition law. The relation of velocity formulae with the coproduct for fourmomenta and noncommutative space-time structure is exhibited.

Post-newtonian Cosmology

Newtonian Cosmology is commonly used in astrophysical problems, because of its obvious simplicity when compared with general relativity. However it has inherent difficulties, the most obvious of which is the non-existence of a well-posed initial value problem. In this paper we investigate how far these problems are met by using the post-Newtonian approximation in cosmology.

Deformed spaces and loop cosmology

The non-singular bouncing solution of loop quantum cosmology is reproduced by a deformed minisuperspace Heisenberg algebra. This algebra is a realization of the Snyder space, is almost unique and is related to the κ-Poincaré one. Since the sign of the deformation parameter it is not fixed, the Friedmann equation of braneworlds theory can also be obtained. Moreover, the sign is the only freedom ...
