The Dirichlet problem for constant mean curvature surfaces in Heisenberg space
Luis J. Alias, Marcos Dajczer, Harold Rosenberg
We study constant mean curvature graphs in the Riemannian 3-dimensional Heisenberg spaces . Each such is the total space of a Riemannian submersion…
Positive parity pentaquark towers in large Nc QCD
Dan Pirjol, Carlos Schat
We construct the complete set of positive parity pentaquarks, which correspond in the quark model to {\bar s} q^{Nc+1} states with one unit of orbital angular momentum L=1. In the…
Spaces of functions with countably many discontinuities
R Haydon, A Molto, J Orihuela
Let be a Polish space and let be a separable and pointwise compact set of real-valued functions on . It is shown that if each function in has only countably many dis…
Bicyclic units, Bass cyclic units and free groups
Jairo Z. Goncalves, Angel del Rio
Let be a finite group and its integral group ring. We show that if is a non-trivial bicyclic unit of , then there are bicyclic units and of different t…
Improved simulation method for the calculation of the intrinsic viscosity of some dendrimer molecules
Esteban Rodriguez, Juan J. Freire, G. del Rio Echenique +2
A method previously proposed for calculating the radius of gyration and the intrinsic viscosity of dendrimers is modified to give a more accurate description of existing experiment…
Quantum loops in radiative decays of the and axial-vector mesons
L. Roca, A. Hosaka, E. Oset
A previous model where the low-lying axial-vector mesons are dynamically generated, implementing unitarity in coupled channels in the vector-pseudoscalar () meson interaction,…
