Critical slowing down in random anisotropy magnets [PDF]

open access: yesCondensed Matter Physics, 2005
We study the purely relaxational critical dynamics with non-conserved order parameter (model A critical dynamics) for three-dimensional magnets with disorder in a form of the random anisotropy axis.

Asymptotic behaviour of total generalised variation [PDF]

open access: yes, 2015
The recently introduced second order total generalised variation functional $\mathrm{TGV}_{\beta,\alpha}^{2}$ has been a successful regulariser for image processing purposes.

Asymptotic behaviour of rational curves

open access: yes, 2011
We investigate the asympotic behaviour of the moduli space of morphisms from the rational curve to a given variety when the degree becomes large. One of the crucial tools is the homogeneous coordinate ring of the variey.

Analysis of the Transient Behaviour in the Numerical Solution of Volterra Integral Equations

open access: yesAxioms, 2021
In this paper, the asymptotic behaviour of the numerical solution to the Volterra integral equations is studied. In particular, a technique based on an appropriate splitting of the kernel is introduced, which allows one to obtain vanishing asymptotic ...

Large positive solutions to an elliptic system of competitive type with nonhomogeneous terms

open access: yesAIMS Mathematics, 2021
In this paper, we study the elliptic system of competitive type with nonhomogeneous terms $ \Delta u = u^pv^q+h_1(x) $, $ \Delta v = u^rv^s+h_2(x) $ in $ \Omega $ with two types of boundary conditions: (Ⅰ) $ u = v = +\infty $ and (SF) $ u = +\infty $, $

Asymptotics of the discrete spectrum for complex Jacobi matrices [PDF]

open access: yesOpuscula Mathematica, 2014
The spectral properties and the asymptotic behaviour of the discrete spectrum for a special class of infinite tridiagonal matrices are given. We derive the asymptotic formulae for eigenvalues of unbounded complex Jacobi matrices acting in \(l^2(\mathbb{N}

On Asymptotics of Optimal Stopping Times

open access: yesMathematics, 2022
We consider optimal stopping problems, in which a sequence of independent random variables is drawn from a known continuous density. The objective of such problems is to find a procedure which maximizes the expected reward.

Asymptotic behaviour of regular estimators

open access: yesRevstat Statistical Journal, 2005
The P.O.T. (Peaks-Over-Threshold) approach consists of using the generalized Pareto distribution (GPD) to approximate the distribution of excesses over thresholds.

A new handle on three-point coefficients: OPE asymptotics from genus two modular invariance

open access: yesJournal of High Energy Physics, 2017
We derive an asymptotic formula for operator product expansion coefficients of heavy operators in two dimensional conformal field theory. This follows from modular invariance of the genus two partition function, and generalises the asymptotic formula for

Asymptotic behaviour of the Urbanik semigroup [PDF]

open access: yes, 2013
We revisit the product convolution semigroup of probability densities e_c(t),c>0 on the positive half-line with moments (n!)^c and determine the asymptotic behaviour of e_c(t) for large and small t>0.
