In this paper: Starting from a family of discontinuous piece-wise linear one-dimensional maps, recently introduced as a dynamic model in social sciences, we propose a geometric method for finding the analytic expres...

In this paper: Higher dimensional cosmological model of the universe is obtained by assuming variable cosmological constant term Λ of the form: and Λ ~ ρ with equation of state p = f(t)ρ. Dynamical behaviors of the...

In this paper: The spherically symmetric dust dominated models, ususlly called Lemaître-Tolman-Bondi models, are investigated. The final/initial behavior of such a Universe is studied in proximity of collapse/genera...

In this paper: We will consider the numerical solution of the Hessenberg linear index-2 differential algebraic equations (DAE’s) using the differential transform method. We will first present a method to reduce the...

In this paper: This paper is dedicated to the study of geometric dynamics (an Euler-Lagrange prolongation of a flow on a Riemannian manifold) from the point of view of KCC theory, Jacobi stability and Lyapounov stab...

In this paper: The suitability of the structure above a high-speed railway bridge beam is analyzed based on the dynamics of moving railroad vehicles. To verify the accuracy of numerical simulation and to establish a...
