Co-occurrence Network of Reuters News
Arzucan Ozgur, Burak Cetin, Haluk Bingol
Networks describe various complex natural systems including social systems. We investigate the social network of co-occurrence in Reuters-21578 corpus, which consists of news artic…
Inversion method for content-based networks
Jose J. Ramasco, Muhittin Mungan
In this paper, we generalize a recently introduced Expectation Maximization (EM) method for graphs and apply it to content-based networks. The EM method provides a classification o…
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…
Primes in Tuples II
D. A. Goldston, J. Pintz, C. Y. Yildirim
We prove that there are infinitely often pairs of primes much closer than the average spacing between primes - almost within the square root of the average spacing. We actually pro…
Bose-Einstein condensate in a harmonic trap with an eccentric dimple potential
Haydar Uncu, Devrim Tarhan, Ersan Demiralp +1
We investigate Bose-Einstein condensation of noninteracting gases in a harmonic trap with an off-center dimple potential. We specifically consider the case of a tight and deep dimp…
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…
