The Inhomogeneous Invariance Quantum Supergroup of Supersymmetry Algebra

Azmi Ali Altintas, Metin Arik

We consider an inhomogeneous quantum supergroup which leaves invariant a supersymmetric particle algebra. The quantum sub-supergroups of this inhomogeneous quantum supergroup are i…

Nonrelativistic Lee model in three dimensional Riemannian manifolds

Fatih Erman, O. Teoman Turgut

In this work, we construct the non-relativistic Lee model on some class of three dimensional Riemannian manifolds by following a novel approach introduced by S. G. Rajeev hep-th/99…

A Note on Intersections of S-branes with p-branes

Nihat Sadik Deger

We first investigate intersections of an S-brane with a single p-brane and show that in addition to the already known solutions, it is possible to place the S-brane so that the rad…

Acceleration of the Universe via f(R) Gravities and The Stability of Extra Dimensions

Tonguç Rador

We discuss the possibility of obtaining the present acceleration of the universe via f(R) gravity theories which recently attracted much attention. It is known that f(R) theories g…

f(R) Gravities à la Brans-Dicke

Tonguç Rador

We extend f(R) theories via the addition of a fundamental scalar field. The approach is reminiscent of the dilaton field of string theory and the Brans-Dicke model. f(R) theories a…

T and S dualities and The cosmological evolution of the dilaton and the scale factors

Tonguç Rador

Cosmologically stabilizing radion along with the dilaton is one of the major concerns of low energy string theory. One can hope that T and S dualities can provide a plausible answe…
