Towards understanding production in collisions
Jiri. Chyla
Understanding the data on the total cross section eeee measured at LEP2 represents a serious challenge for perturbative QCD. In order to unrav…
Inelastically scattering particles and wealth distribution in an open economy
Frantisek Slanina
Using the analogy with inelastic granular gasses we introduce a model for wealth exchange in society. The dynamics is governed by a kinetic equation, which allows for self-similar…
Associahedra, cellular W-construction and products of -algebras
Martin Markl, Steve Shnider
Our aim is to construct a functorial tensor product of -algebras or, equivalently, an explicit diagonal for the operad of cellular chains, over the integers, of the Stash…
Exponential splitting of bound states in a waveguide with a pair of distant windows
D. Borisov, P. Exner
We consider Laplacian in a straight planar strip with Dirichlet boundary which has two Neumann ``windows'' of the same length the centers of which are apart, and study the asy…
Convergence of spectra of graph-like thin manifolds
Pavel Exner, Olaf Post
We consider a family of compact manifolds which shrinks with respect to an appropriate parameter to a graph. The main result is that the spectrum of the Laplace-Beltrami operator c…
Stability of solutions of the Sherrington-Kirkpatrick model with respect to replications of the phase space
V. Janis
We use real replicas within the Thouless, Anderson and Palmer construction to investigate stability of solutions with respect to uniform scalings in the phase space of the Sherring…
