Agglomeration and Growth in the NEG: A Critical Assessment [PDF]

open access: yes, 2007
This chapter is divided into two parts. In the first part we review the main results of a typical "New Economic Geography and Growth" (NEGG) model (Baldwin and Martin, 2003) and assess the contribution of this literature to the issue of long-run income gaps between countries.

Multi-bump solutions for the magnetic Schrödinger–Poisson system with critical growth

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2022
In this paper, we are concerned with the following magnetic Schrödinger–Poisson system \begin{align*} \begin{cases} -(\nabla+i A(x))^{2}u+(\lambda V(x)+1)u+\phi u=\alpha f(\left | u\right |^{2})u+\vert u\vert^{4}u,& \text{ in }\mathbb{R}^{3}, \\ -\Delta \

Choquard-type equations with Hardy–Littlewood–Sobolev upper-critical growth

open access: yesAdvances in Nonlinear Analysis, 2018
We are concerned with the existence of ground states and qualitative properties of solutions for a class of nonlocal Schrödinger equations. We consider the case in which the nonlinearity exhibits critical growth in the sense of the Hardy–Littlewood ...

Positive solutions of a Kirchhoff–Schrödinger--Newton system with critical nonlocal term

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2022
This paper deals with the following Kirchhoff–Schrödinger–Newton system with critical growth \begin{equation*} \begin{cases} \displaystyle-M\left(\int_{\Omega}|\nabla u|^2dx\right)\Delta u=\phi |u|^{2^*-3}u+\lambda|u|^{p-2}u, &\rm \mathrm{in ...

A class of semipositone p-Laplacian problems with a critical growth reaction term [PDF]

open access: yesAdvances in Nonlinear Analysis, 2016
We prove the existence of ground state positive solutions for a class of semipositone p-Laplacian problems with a critical growth reaction term. The proofs are established by obtaining crucial uniform C1,α a priori estimates and by concentration ...

Ground states for a fractional scalar field problem with critical growth [PDF]

open access: yesDifferential and Integral Equations, 2016
We prove the existence of a ground state solution for the following fractional scalar field equation $(-\Delta)^{s} u= g(u)$ in $\mathbb{R}^{N}$ where $s\in (0,1), N> 2s$,$ (-\Delta)^{s}$ is the fractional Laplacian, and $g\in C^{1, \beta}(\mathbb{R ...

Ground state and multiple solutions for critical fractional Schrodinger-Poisson equations with perturbation terms

open access: yesElectronic Journal of Differential Equations, 2021
In this article, we study a class of critical fractional Schrodinger-Poisson system with two perturbation terms. By using variational methods and Lusternik-Schnirelman category theory, the existence of ground state and two nontrivial solutions are ...

Slip Line Growth as a Critical Phenomenon

open access: yesPhysical Review Letters, 2009
We study the growth of slip line in a plastically deforming crystal by numerical simulation of a double-ended pile-up model with a dislocation source at one end, and an absorbing wall at the other end. In presence of defects, the pile-up undergoes a second order non-equilibrium phase transition as a function of stress, which can be characterized by ...

Ground state solutions for a fractional Schrödinger equation with critical growth [PDF]

open access: yesAsymptotic Analysis, 2016
In this paper we investigate the existence of nontrivial ground state solutions for the following fractional scalar field equation \begin{align*} (-\Delta)^{s} u+V(x)u= f(u) \mbox{ in } \mathbb{R}^{N}, \end{align*} where $s\in (0,1)$, $N> 2s$, $(-\Delta)^
