On Elliptic Problems Involving Critical Hardy - Sobolev Exponents And Sign-changing Function

Rodrigues R.D.S. (, 2010)

Lyapunov-type inequalities: with applications to eigenvalue problems

Pinasco, Juan Pablo (Springer, 2013)

Introduction The eigenvalue problems for quasilinear and nonlinear operators present many differences with the linear case, and a Lyapunov inequality for quasilinear resonant systems showed the existence of eigenvalue ...

A-posterirori error estimates for linear exterior problems via mixed-FEM and DtN mappings.

Autor desconocido (2002)

In this paper we combine the dual-mixed finite element method with a Dirichlet-to-Neumann mapping (given in terms of a boundary integral operator) to solve linear exterior transmission problems in the plane. As a model we ...

Warm ionized gas in CALIFA early-type galaxies 2D emission-line patterns and kinematics for 32 galaxies

Gomes, J.M.; Papaderos, P.; Kehrig, C.; Vílchez, J. M.; Lehnert, M. D.; Sánchez, S. F.; Ziegler, B.; Breda, I.; dos Reis, S.N.; Iglesias-Páramo, J.; Bland-Hawthorn, J.; Galbany, Lluis; Bomans, D. J.; Rosales-Ortega, F. F.; Cid Fernandes, R.; Walcher, C. J.; Falcón Barroso, J.; García-Benito, R.; Márquez, I.; Olmo, A. del; Masegosa, J.; Mollá, M.; Marino, R. A.; González Delgado, R. M.; López Sánchez, Ángel R. (ESO, 2016-04)

Context. The morphological, spectroscopic, and kinematical properties of the warm interstellar medium (wim) in early-type galaxies (ETGs) hold key observational constraints to nuclear activity and the buildup history of ...

Fractional Derivative Estimates In Gevrey Spaces, Global Regularity And Decay For Solutions To Semilinear Equations In ℝn

Biagioni H.A.; Gramchev T. (, 2003)

Representación integral de soluciones de problemas no locales

Agudelo Parra, Nelson Andrés (Universidad Nacional de ColombiaMedellín - Ciencias - Maestría en Ciencias - MatemáticasFacultad de CienciasMedellín, ColombiaUniversidad Nacional de Colombia - Sede Medellín, 2022-09)

En este trabajo estudiamos un problema semilineal que involucra un operador de tipo no local a través de la transformada de Fourier. Investigamos existencia y unicidad local de soluciones vía el principio de Duhamel y las ...

Existence of positive solutions for a Semipositone fractional p-Laplacian problem

López Morales, Camila (Universidad Nacional de ColombiaManizales - Ciencias Exactas y Naturales - Maestría en Ciencias - Matemática AplicadaFacultad de Ciencias Exactas y NaturalesManizales, ColombiaUniversidad Nacional de Colombia - Sede Manizales, 2023)

In this thesis we will make a brief study of Fractional Sobolev spaces. We will give two equivalent de nitions of these spaces using interpolation spaces and the Fourier transform in the case p = 2. Finally, we prove the ...

Variations for Some Painlevé Equations

Acosta-Humañez, Primitivo B.; Van Der Put, Marius; Top, Jaap (SIGMA, 2019)

This paper rst discusses irreducibility of a Painlev e equation P. We explain how the Painlev e property is helpful for the computation of special classical and algebraic solutions. As in a paper of Morales-Ruiz we ...
