Tight contact structures on some small Seifert fibered 3--manifolds
Paolo Ghiggini, Paolo Lisca, Andras I. Stipsicz
We classify tight contact structures on the small Seifert fibered 3--manifold M(-1; r_1, r_2, r_3) with r_i in (0,1) and r_1, r_2 \geq 1/2. The result is obtained by combining conv…
Weak convergence of finite graphs, integrated density of states and a Cheeger type inequality
Gábor Elek
In \cite{Elek} we proved that the limit of a weakly convergent sequence of finite graphs can be viewed as a graphing or a continuous field of infinite graphs. Thus one can associat…
Basic characterization of highly enriched uranium by gamma spectrometry
Cong Tam Nguyen, Jozsef Zsigrai
Gamma-spectrometric methods suitable for the characterization of highly enriched uranium samples encountered in illicit trafficking of nuclear materials are presented. In particula…
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…
Self-organization of atoms in a cavity field: threshold, bistability and scaling laws
J. K. Asboth, P. Domokos, H. Ritsch +1
We present a detailed study of the spatial self-organization of laser-driven atoms in an optical cavity, an effect predicted on the basis of numerical simulations [P. Domokos and H…
On the distribution of the modulation frequencies of RR Lyrae stars
Johanna Jurcsik, Béla Szeidl, Andrea Nagy +1
For the first time connection between the pulsation and modulation properties of RR Lyrae stars has been detected. Based on the available data it is found that the possible range o…
