Asymptotic behaviours of stochastic differential delay equations [PDF]

open access: yes, 2006
Most of the existing results on stochastic stability use a single Lyapunov function, but we shall instead use multiple Lyapunov functions in this paper.

Multiple scale asymptotics of map enumeration

open access: yesNonlinearity, 2023
Abstract We introduce a systematic approach to express generating functions for the enumeration of maps on surfaces of high genus in terms of a single generating function relevant to planar surfaces. Central to this work is the comparison of two asymptotic expansions obtained from two different fields of mathematics: the Riemann–Hilbert ...

Scaled asymptotics for some q-functions

open access: yesAdvances in Applied Mathematics, 2012
In 2006-2007, the author and M. E. Ismail applied a new method to Plancherel-Rotach type asymptotics for certain sets of orthogonal polynomials. Later, in 2008, the author extended the method to study certain Plancherel-Rotach type asymptotics for some \(q\)-series.

Statistical Analysis of Multi-Relational Network Recovery

open access: yesFrontiers in Applied Mathematics and Statistics, 2020
In this paper, we develop asymptotic theories for a class of latent variable models for large-scale multi-relational networks. In particular, we establish consistency results and asymptotic error bounds for the (penalized) maximum likelihood estimators ...

The middle-scale asymptotics of Wishart matrices [PDF]

open access: yesThe Annals of Statistics, 2019
We study the behavior of a real $p$-dimensional Wishart random matrix with $n$ degrees of freedom when $n,p\rightarrow\infty$ but $p/n\rightarrow 0$. We establish the existence of phase transitions when $p$ grows at the order $n^{(K+1)/(K+3)}$ for every $k\in\mathbb{N}$, and derive expressions for approximating densities between every two phase ...

Asymptotic scaling from strong coupling [PDF]

open access: yesPhysical Review D, 1995
Strong-coupling analysis of two-dimensional chiral models, extended to 15th order, allows for the identification of a scaling region where known continuum results are reproduced with great accuracy, and asymptotic scaling predictions are fulfilled. The properties of the large-$N$ second-order phase transition are quantitatively investigated.

ASYMPTOTIC SCALING SYMMETRIES FOR NONLINEAR PDES [PDF]

open access: yesInternational Journal of Geometric Methods in Modern Physics, 2005
In some cases, solutions to nonlinear PDEs happen to be asymptotically (for large x and/or t) invariant under a group G which is not a symmetry of the equation. After recalling the geometrical meaning of symmetries of differential equations — and solution-preserving maps — we provide a precise definition of asymptotic symmetries of PDEs; we deal in ...

No asymptotic acceleration without higher-dimensional de Sitter vacua

open access: yesJournal of High Energy Physics, 2023
There has recently been considerable interest in the question whether and under which conditions accelerated cosmological expansion can arise in the asymptotic regions of field space of a d-dimensional EFT.
