Semiclassical stationary states for nonlinear Schr\"odinger equations under a strong external magnetic field [PDF]

open access: yes, 2015
We construct solutions to the nonlinear magnetic Schr\"odinger equation $$ \left\{ \begin{aligned} - \varepsilon^2 \Delta_{A/\varepsilon^2} u + V u &= \lvert u\rvert^{p-2} u & &\text{in}\ \Omega,\\ u &= 0 & &\text{on}\ \partial\Omega, \end{aligned}

New results on the continuous Weinstein wavelet transform

open access: yesJournal of Inequalities and Applications, 2017
We consider the continuous wavelet transform S h W $\mathcal{S}_{h}^{W}$ associated with the Weinstein operator. We introduce the notion of localization operators for S h W $\mathcal {S}_{h}^{W}$ .

Connecting the realms of urban form, density and microclimate [PDF]

open access: yes, 2018
Av doktorgradsstudenter på norske universiteter, er det en fjerdedel som ikke fullfører innen normert tid. Det er lite forskning på hvorfor det er slik i Norge.

Morphometric analysis of sub-basins Fojo and Perdizes in the city of Campos do Jordão, SP, Brazil

open access: yesRevista Ambiente & Água, 2012
The State of São Paulo Water Resources Policy established, in 1991, the Integrated Water Resources Management System (SIGRHI) and defined the basic principles for water management, adopting the watershed as the basic unit for studies, integrated planning

Some Progress in Conformal Geometry [PDF]

open access: yes, 2007
This is a survey paper of our current research on the theory of partial differential equations in conformal geometry. Our intention is to describe some of our current works in a rather brief and expository fashion.

Existence of minimizers for Kohn-Sham within the Local Spin Density Approximation [PDF]

open access: yes, 2014
The purpose of this article is to extend the work by Anantharaman and Canc\`es [1], and prove the existence of minimizers for the spin-polarized Kohn-Sham model in the presence of a magnetic field within the local spin density approximation. We show that

Image reconstruction in optical interferometry: Benchmarking the regularization [PDF]

open access: yes, 2011
With the advent of infrared long-baseline interferometers with more than two telescopes, both the size and the completeness of interferometric data sets have significantly increased, allowing images based on models with no a priori assumptions to be ...

Concentration-compactness at the mountain pass level in semilinear elliptic problems

open access: yes, 2007
The concentration compactness framework for semilinear elliptic equations without compactness, set originally by P.-L.Lions for constrained minimization in the case of homogeneous nonlinearity, is extended here to the case of general nonlinearities in ...

Improved Sobolev embeddings, profile decomposition, and concentration-compactness for fractional Sobolev spaces

open access: yes, 2013
We obtain an improved Sobolev inequality in H^s spaces involving Morrey norms. This refinement yields a direct proof of the existence of optimizers and the compactness up to symmetry of optimizing sequences for the usual Sobolev embedding. More generally,

Dark matter concentrations in galactic nuclei according to polytropic models [PDF]

open access: yes, 2016
We calculate the radial profiles of galaxies where the nuclear region is self-gravitating, consisting of self-interacting dark matter (SIDM) with $F$ degrees of freedom.
