Gamma convergence of an energy functional related to the fractional Laplacian
González Nogueras, María del Mar (2009)
Article
Accés restringit per política de l'editorialWe prove a Γ -convergence result for an energy functional related to some fractional powers of the Laplacian operator, (−Δ)s for 1/2 < s < 1, with two singular perturbations, that leads to a two-phase problem. The case ... -
Instability and bifurcation in a trend depending price formation model
González Nogueras, María del Mar; Gualdani, Maria Pia; Solà-Morales Rubió, Joan de (2016-08)
Article
Accés obertA well-known model due to J.-M. Lasry and P.L. Lions that presents the evolution of prices in a market as the evolution of a free boundary in a diffusion equation is modified in order to show instabilities for some values ... -
Layer solutions for the fractional Laplacian on hyperbolic space
González Nogueras, María del Mar (2013)
Text en actes de congrés
Accés obertThe workshop dealt with partial differential equations in ge om- etry and technical applications. The main topics were the co mbination of nonlinear partial differential equations and geometric pro blems, and fourth order ... -
Layer solutions for the fractional Laplacian on hyperbolic space: existence, uniqueness and qualitative properties
González Nogueras, María del Mar; Saéz, Mariel; Sire, Yannick (2012-12)
Report de recerca
Accés obertwhere (¿ Hn) corresponds to the fractional Laplacian on hyperbolic space for 2 (0; 1) and f is a smooth nonlinearity that typically comes from a double well potential. We prove the existence of heteroclinic connections ... -

Article
Accés restringit per política de l'editorialWe investigate the equation; (-Delta(Hn))(gamma) w = f(w) in H-n,; where (-Delta(Hn))(gamma) corresponds to the fractional Laplacian on hyperbolic space for gamma is an element of(0, 1) and f is a smooth nonlinearity that ... -
Renormalized weighted volume for the conformal fractional Laplacian
González Nogueras, María del Mar (2011-07)
Report de recerca
Accés obertWe give a notion of renormalized weighted volume in the setting of conformal geometry following the ideas of Fefferman-Graham. Indeed, it is a precise term in the asymptotic expansion near the boundary for a weighted ... -
Singularities for a fully non-linear elliptic equation in conformal geometry
González Nogueras, María del Mar; Mazzieri, Lorenzo (2013-08)
Report de recerca
Accés obertWe construct some radially symmetric solutions of the constant k -equation on R n n R p , which blow up exactly at the submanifold R p R n . These are the basic models to the problem of nding complete metrics ... -

Slow motion of particle systems as a limit of a reaction-diffusion equation with fractional Laplacian
González Nogueras, María del Mar; Monneau, R. (2010-07)
Report de recerca
Accés obertWe consider a reaction-diffusion equation with a half-Laplacian. In the case where the solution is independent on time, the model reduces to the Peierls-Nabarro model describing dislocations as transition layers in a ... -
Some constructions for the fractional Laplacian on noncompact manifolds
Banica, Valeria; González Nogueras, María del Mar; Saéz, Mariel (2015-01-01)
Article
Accés obertWe give a definition of the fractional Laplacian on some noncompact manifolds, through an extension problem introduced by Caffarelli-Silvestre. While this definition in the compact case is straightforward, in the noncompact ... -

Report de recerca
Accés obertWe give a de nition of the fractional Laplacian on some noncompact manifolds, through an extension problem introduced by Ca arelli-Silvestre. While this de nition in the compact case is straightforward, in the noncompact ... -
Some non-standard sobolev spaces, interpolation and its application to PDE
González Nogueras, María del Mar; Gualdani, Maria (2012-10)
Article
Accés restringit per política de l'editorialWe consider some nonstandard Sobolev spaces in one dimension, in which functions have different regularity in different subsets. These spaces are useful in the study of some nonlinear parabolic equations where the ... -

González Nogueras, María del Mar; Gualdani, Maria (2009-06)
Report de recerca
Accés obertWe consider some nonstandard Sobolev spaces in one dimension, in which functions have different regularity in different subsets. Those spaces are useful in the study of some nonlinear elliptic and parabolic equations where ...
