Dynamical Critical Exponent for Two-Species Totally Asymmetric Diffusion on a Ring

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2010
We present a study of the two species totally asymmetric diffusion model using the Bethe ansatz. The Hamiltonian has U_q(SU(3)) symmetry. We derive the nested Bethe ansatz equations and obtain the dynamical critical exponent from the finite-size scaling ...

Solutions of p(x)-Laplacian equations with critical exponent and perturbations in R^N

open access: yesElectronic Journal of Differential Equations, 2012
Based on the theory of variable exponent Sobolev spaces, we study a class of $p(x)$-Laplacian equations in $mathbb{R}^{N}$ involving the critical exponent.

Mapped Exponent and Asymptotic Critical Exponent of Words

open access: yes
We study how much injective morphisms can increase the repetitiveness of a given word. This question has a few possible variations depending on the meaning of ``repetitiveness''. We concentrate on fractional exponents of finite words and asymptotic critical exponents of infinite words.

Existence Results for Singular p-Biharmonic Problem with HARDY Potential and Critical Hardy-Sobolev Exponent

open access: yesAxioms
In this article, we consider the singular p-biharmonic problem involving Hardy potential and critical Hardy–Sobolev exponent. Firstly, we study the existence of ground state solutions by using the minimization method on the associated Nehari manifold ...

Two critical localization lengths in the Anderson transition on random graphs

open access: yesPhysical Review Research, 2020
We present a full description of the nonergodic properties of wave functions on random graphs without boundary in the localized and critical regimes of the Anderson transition. We find that they are characterized by two critical localization lengths: the

Vulcanization and critical exponents [PDF]

open access: yesJournal de Physique Lettres, 1979
We consider a particular case of vulcanization of polymer chains in a semi dilute solution where a concentration p of vulcanizing agent has been added. This problem is equivalent to the percolation of elements having a functionality f depending both on the length N of the initial chains and on the monomer concentration C. Our approach allows us to take

Probing thermodynamic phase transitions of 4D R-charged black holes via lyapunov exponent

open access: yesNuclear Physics B
We investigate the thermodynamic phase structure of four-dimensional R-charged black holes–characterized by four independent U(1) charges–through the lens of Lyapunov exponents associated with unstable circular orbits of both massless and massive ...

Critical exponent and discontinuous nonlinearities

open access: yesDifferential and Integral Equations, 1993
We prove existence of a positive solution to the problem \[ -\Delta u=| u|^{2^*- 2} u+bh (u-a), \quad u(x)>0 \;\;\text{in }\Omega, \quad u(x)=0\;\;\text{on } \partial\Omega, \tag{1} \] where \(\Omega\) is a bounded regular open set \(\subset \mathbb{R}^ N\), \(2^*= {{2N} \over {n-2}}\) is the critical Sobolev exponent, \(h\) is the Heaviside function ...

CRITICAL EXPONENTS OF ERBIUM

open access: yesLe Journal de Physique Colloques, 1988
The exponent β that describes the sinusoidally modulate d ↔ paramagnetic phase transition crosses over from a value of 0.39 near TN to a mean field value away from TN. Electrical resistivity measurements near TN are given for the c axis and the critical behaviour is discussed.
