Modeling innovation by a kinetic description of the patent citation system
Gabor Csardi, Katherine J Strandburg, Laszlo Zalanyi +2
This paper reports results of a network theory approach to the study of the United States patent system. We model the patent citation network as a discrete time, discrete space sto…
An analytic approach to the late ISW effect in a Lambda dominated universe
Viktor Czinner, Mátyás Vasúth, Árpád Lukács
The integrated Sachs-Wolfe (ISW) effect in a Lambda dominated universe can be an important factor in the evolution of cosmic microwave background fluctuations. With the inclusion o…
Covariant description of kinetic freeze out through a finite space-like layer
E. Molnar, L. P. Csernai, V. K. Magas +2
The problem of Freeze Out (FO) in relativistic heavy ion reactions is addressed. We develop and analyze an idealized one-dimensional model of FO in a finite layer, based on the cov…
Covariant Linear Perturbations in a Concordance Model
Viktor Czinner, Mátyás Vasúth, Árpád Lukács +1
We present the complete solution of the first order metric and density perturbation equations in a spatially flat (K=0), Friedmann-Robertson-Walker (FRW) universe filled with press…
Finitary Galois extensions over noncommutative bases
I. Balint, K. Szlachanyi
We study Galois extensions Coinv(M)<M for M an H-comodule algebra and H a Frobenius Hopf algebroid. We obtain generalizations of various theorems in Hopf-Galois theory by Kreimer-T…
Entanglement in the XX spin chain with an energy current
V. Eisler, Z. Zimboras
We consider the ground state of the XX chain that is constrained to carry a current of energy. The von Neumann entropy of a block of neighboring spins, describing entanglement…
