Infinite first order differential systems with nonlocal initial conditions
Gennaro Infante, Petru Jebelean, Fadila Madjidi
We discuss the solvability of an infinite system of first order ordinary differential equations on the half line, subject to nonlocal initial conditions. The main result states tha…
Electronic structure and crystal phase stability of palladium hydrides
Abdesalem Houari, Samir F. Matar, Volker Eyert
The results of electronic structure calculations for a variety of palladium hydrides are presented. The calculations are based on density functional theory and used different local…
Modified gravity from an entropy functional
Fayçal Hammad
We extend Padmanabhan's entropy functional formalism to show that, in addition to the Gauss-Bonnet or the entire series of Lanczos-Lovelock Lagrangians already obtained, more gener…
Quantization of soluble classical constrained systems
Zahir Belhadi, Ferhat Ménas, Alain Bérard +1
The derivation of the brackets among coordinates and momenta for classical constrained systems is a necessary step toward their quantization. Here we present a new approach for the…
A (varying power)-law modified gravity
Fayçal Hammad
In the present paper we analyze a toy model for an gravity which has the form of a power-law modified gravity in which the exponent is space-time dependent. Namely, we inv…
