Torelli theorem for the Deligne--Hitchin moduli space
Indranil Biswas, Tomas L. Gomez, Norbert Hoffmann +1
Fix integers and , with if . Given a compact connected Riemann surface of genus , let $\MDH(X)$ denote the corresponding $\text{SL}(r, {\ma…
Vortex dynamics in confined stratified conditions
Farkhad G. Aliev, Juan F. Sierra, Ahmad A. Awad +6
We report on linear spin dynamics in the vortex state of the Permalloy dots subjected to stratified (magnetic) field. We demonstrate experimentally and by simulations the existence…
Spitzer--IRAC Imagery and Photometry of Ultracompact HII Regions With Extended Emission
E. de la Fuente, A. Porras, J. M. C. Grave +6
We present the results of a morphological study performed to a sample of Ultracompact (UC) HII regions with Extended Emission (EE) using Spitzer--IRAC imagery and 3.6 cm VLA conf.…
No evidence for mass segregation in massive young clusters
J. Ascenso, J. Alves, M. T. V. T. Lago
Aims. We investigate the validity of the mass segregation indicators commonly used in analysing young stellar clusters. Methods. We simulate observations by constructing synthetic…
Finite Volume Spectrum of 2D Field Theories from Hirota Dynamics
Nikolay Gromov, Vladimir Kazakov, Pedro Vieira
We propose, using the example of the O(4) sigma model, a general method for solving integrable two dimensional relativistic sigma models in a finite size periodic box. Our starting…
Bifurcation and pattern changing with two real scalar fields
P. P. Avelino, D. Bazeia, R. Menezes +1
This work deals with bifurcation and pattern changing in models described by two real scalar fields. We consider generic models with quartic potentials and show that the number of…
