In this paper: The concept of dynamic equivalence of nonlinear time-variant systems defined on discrete-time scales is introduced. There are studied relations between classical static state feedback and external dyn...

In this paper: The aim of this paper is to construct a natural Riemann-Lagrange differential geometry on 1-jet spaces, in the sense of nonlinear connections, generalized Cartan connections, d-torsions, d-curvatures,...

In this paper: A special Frenet motion with a one parameter has been given by Bottema [5] in E3. In this study, we have given a generalization of [5] to Bishop motion in Euclidean 3-space. Firstly, Bishop motion is...

In this paper: In this paper, we consider non-linear perturbation for the third order linear oscillator. Using the center manifold reduction, we reduced system into second order differential equation. Then we study...

In this paper: We will consider the solution of Hessenberg index-2 differential algebraic equations(DAE) numerically. We first introduce a method to reduce the index from 2 to index 1 resulting in an easier problem...

In this paper: We have analysed Kaluza Klein type five dimensional cosmological model by considering three different forms of variable and Λ ~ ρ. It is found that, the connecting free parameters of the models with c...

In this paper: Dynamically defined topological pressure as an extension of the notion of topological pressure for a non compact metric space with a semidynamics is presented. The semi-dynamics of the state space is...

In this paper: In this paper by using of immersed hypergroups and hyperdynamical systems the notion of immersed hyperdynamical system is considered. Quotient immersed hyperdynamical systems are studied.

In this paper: In Newman-Penrose formalism, the ten independent components of the Weyl tensor can be expressed in terms of five complex scalars Ψundefined (r = 0, 1, 2, 3, 4). By a suitable choice of the tetrad, we...

In this paper: In this paper by using a special kind of dynamics on a metric space, the notion of topological entropy is developed. The independence of ”dynamically defined topological entropy” of the choice of base...
