Resumen : We consider constant boundary conditions (cbc) for the Ablowitz-Kaup-Newell-Segur(AKNS) system in the framework of the sl(2) affine Kac-Moody algebra formulation. Through the dressing transformation and the tau function approach we obtain its soliton solutions and classify them according to their regular or singular behaviors. Moreover, by the analytic continuation method it is obtained the dark soliton solution of the well-known nonlinear Schrodinger equation (NLS) with cbc, which turns out to be a submodel of the AKNS system.2012-12-01T00:00:00ZGeneralized AKNS System, Non-vanishing Boundary Conditions and N-Dark-Dark SolitonsDe O.

Resumen : We consider certain boundary conditions supporting soliton solutions in the generalized non-linear Schrodinger equation (AKNS). Using the dressing transformation (DT) method and the related tau functions we study the AKNSr system for the vanishing, (constant) non-vanishing and the mixed boundary conditions, and their associated bright, dark and bright-dark N-soliton solutions, respectively. Moreover, we introduce a modified DT related to the dressing group in order to consider the free field boundary condition and derive generalized N-dark-dark solitons. We have shown that two-dark-dark-soliton bound states exist in the AKNS2 system, and three and higher-dark-dark-soliton bound states can not exist. As a reduced submodel of the AKNSr system we study the properties of the focusing, defocusing and mixed focusing-defocusing versions of the so-called coupled non-linear Schrodinger equation (r-CNLS), which has recently been considered in many physical applications. The properties and calculations of some matrix elements using level one vertex operators are outlined.2012-12-01T00:00:00ZOA- UNI: an Astronomical Observatory at UNIPereyra, A.Cori, W.Meza, E.Ricra, J.Granda, G.http://hdl.handle.net/20.500.14076/174392019-05-09T07:52:20Z2012-12-01T00:00:00ZTítulo : OA- UNI: an Astronomical Observatory at UNI

Resumen : We summarized the status of an ongoing project which aims to implement an astronomical observatory for the Faculty of Science of the National University of Engineering (FC-UNI). This observatory (OA-UNI) will be installed at the peruvian central Andes using the facilities of the Instituto Geofisico del Peru at Huancayo. We shown examples of science projects that could be initiated along with the future perspectives for its upgrade. We also comment the impact of the OA-UNI to open new possibilities to develop pre-professionals training in astronomy for last-year students at FC-UNI.2012-12-01T00:00:00Z
