Half-Yearly Journal: Publishes research on dynamical systems and geometry, including Random Dynamical Systems, hyperbolic behaviour, complex geometry and Ergodic theory.
In this paper: In this paper we consider the extended Chaplygin gas equation of state as a model of dark energy for which it recovers barotropic fluids with quadratic equation of state. We obtain scale factor depend...

In this paper: This paper concerns the chaos game of random iterated function systems. We consider a random iterated function system IFS() generated by a finite family of Lipschitz maps on a compact ball of ℝundefin...

In this paper: Suppose that = (MM ) is a graded manifold and consider a direct subsheaf of Derundefined and a graded vector field Γ on ; both satisfying certain conditions. We associate to the graded vector field Γ...
In this paper: In this paper, we considered the cosmological application by taking G and Λ to be a function of t in Kaluza-Klein cosmology. We use the Taylor’s expansion of cosmological function Λ(t), up to the firs...

In this paper: It is well-known that Einstein manifolds play an important role in geometry as well as in general relativity. Einstein manifolds form a natural subclass of the class of quasi-Einstein manifolds. The o...

In this paper: In this paper we consider a correspondence between holographic dark energy density and extended Chaplygin gas energy density proposed by Pourhassan and Kahya [2014] (Advances in High Energy Physics, 2...

In this paper: In a recent article [J. d' Analyse Math131, 207, 2017], Olsen intoduced a generalized notion of multifractal pressure, and also a multifractal dynamical zeta function, which essentilly consists in con...
