On perturbation theory and critical exponents for self-similar systems

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
Gravitational critical collapse in the Einstein-axion-dilaton system is known to lead to continuous self-similar solutions characterized by the Choptuik critical exponent $$\gamma $$ γ . We complete the existing literature on the subject by computing the

Existence of solution for a quasilinear elliptic Neumann problem involving multiple critical exponents

open access: yesBoundary Value Problems, 2020
In this paper, we study the Neumann boundary value problem to a quasilinear elliptic equation with the critical Sobolev exponent and critical Hardy–Sobolev exponent, and prove the existence of nontrivial nonnegative solution by means of variational ...

Critical Tsallis exponent in heavy ion reaction [PDF]

open access: yes, 2001
The numerical solution of the nonlocal kinetic equation allows to simulate heavy ion reactions around Fermi energy. The expansion velocity and density profile show specific radial dependence which can be described with a Tsallis exponent of $q=5/3$. This

Noether Symmetries and Critical Exponents [PDF]

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2005
We show that all Lie point symmetries of various classes of nonlinear differential equations involving critical nonlinearities are variational/divergence symmetries.

Normalized solutions for nonlinear Kirchhoff type equations in high dimensions

open access: yesElectronic Research Archive, 2022
We study the normalized solutions for nonlinear Kirchhoff equation with Sobolev critical exponent in high dimensions $ \mathbb{R}^N(N\geqslant4) $. In particular, in dimension $ N = 4 $, there is a special phenomenon for Kirchhoff equation that the mass ...

Inhomogeneous Neumann problem with critical Sobolev exponent

open access: yesAdvances in Nonlinear Analysis, 2012
We investigate the solvability of the inhomogeneous Neumann problem involving the critical Sobolev exponent. In particular, we discuss the impact of the shape of the graph of the coefficient of the critical exponent on the existence of a solution.

The dynamic exponent of the Ising model on negatively curved surfaces [PDF]

open access: yes, 2006
We investigate the dynamic critical exponent of the two-dimensional Ising model defined on a curved surface with constant negative curvature. By using the short-time relaxation method, we find a quantitative alteration of the dynamic exponent from the ...

Critical exponent for the Anderson transition in the three-dimensional orthogonal universality class

open access: yesNew Journal of Physics, 2014
We report a careful finite size scaling study of the metal–insulator transition in Anderson's model of localization. We focus on the estimation of the critical exponent ν that describes the divergence of the localization length.
