Asymptotic Expansions for Sub-Critical Lagrangean Forms [PDF]

open access: yes, 2018
Asymptotic expansions for the Taylor coefficients of the Lagrangean form phi(z)=zf(phi(z)) are examined with a focus on the calculations of the asymptotic coefficients.

Approximation formulas related to Somos’ quadratic recurrence constant

open access: yesJournal of Inequalities and Applications, 2018
We present two classes of asymptotic expansions related to Somos’ quadratic recurrence constant and provide the recursive relations for determining the coefficients of each class of the asymptotic expansions by using Bell polynomials and other techniques.

Recurrence coefficients of Toda-type orthogonal polynomials I. Asymptotic analysis [PDF]

open access: yesBulletin of Mathematical Sciences, 2020
We study the three-term recurrence coefficients βn,γn, of polynomial sequences orthogonal with respect to a perturbed linear functional depending on a variable z. We obtain power series expansions in z, and asymptotic expansions as n →∞.

Asymptotic expansions for Yosida approximations of semigroups

open access: yesLietuvos Matematikos Rinkinys, 2008
In this paper we provide asymptotic expansions for Yosida approximations of contraction semigroups. We also obtain optimal bounds for convergencerate and remainder terms of asymptotic expansions.

Nadinebejjani/Asymptotic-Expansions: Asymptotic expansions for modelling wave propagation in composite plates

open access: yes, 2020
We provide here a MATLAB code that allows the computation of the compressional, in-plane shear and flexural dispersion curves, corresponding to waves propagating in infinite composite plates, through the asymptotic expansion ...

On second-order differential equations with highly oscillatory forcing terms [PDF]

open access: yes, 2010
We present a method to compute efficiently solutions of systems of ordinary differential equations that possess highly oscillatory forcing terms. This approach is based on asymptotic expansions in inverse powers of the oscillatory parameter,and features ...

Extremal properties of the beta-normal distribution

open access: yesJournal of Inequalities and Applications, 2022
Asymptotic behaviors of the extremes of the beta-normal distribution are derived. The higher-order asymptotic expansions of the probability density and cumulative distribution functions for the maximum are given under an optimal normalizing constants. In

Generalised Asymptotic Solutions for the Inflaton in the Oscillatory Phase of Reheating

open access: yesUniverse, 2021
We determine generalised asymptotic solutions for the inflaton field, the Hubble parameter, and the equation-of-state parameter valid during the oscillatory phase of reheating for potentials that close to their global minima behave as even monomial ...
