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

On an asymptotic formula for the niven numbers

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1985
A Niven number is a positive integer which is divisible by its digital sum. A discussion of the possibility of an asymptotic formula for N(x) is given. Here, N(x) denotes the nmber of Niven numbers less than x. A partial result will be presented.

Consistency and Asymptotic Normality of the Maximum Likelihood Estimator in GaGLM

open access: yesIEEE Access, 2022
The Gamma distribution based generalized linear model ( $Ga$ GLM) is a kind of statistical model feasible for the positive value of a non-stationary stochastic system, in which the location and the scale are regressed by the corresponding explanatory ...

An asymptotic formula for integer points on Markoff-Hurwitz varieties [PDF]

open access: yesAnnals of Mathematics, 2016
We establish an asymptotic formula for the number of integer solutions to the Markoff-Hurwitz equation x21+x22+⋯+x2n=ax1x2⋯xn+k. When n≥4, the previous best result is by Baragar (1998) that gives an exponential rate of growth with exponent β that is ...

Higher-Order Asymptotic Numerical Solutions for Singularly Perturbed Problems with Variable Coefficients

open access: yesMathematics, 2022
For the purpose of solving a second-order singularly perturbed problem (SPP) with variable coefficients, a mth-order asymptotic-numerical method was developed, which decomposes the solutions into two independent sub-problems: a reduced first-order linear

An asymptotic formula for the number of irreducible transformation shift registers [PDF]

open access: yesarXiv.org, 2015
We consider the problem of enumerating irreducible transformation shift registers. We give an asymptotic formula for the number of irreducible transformation shift registers in some special cases. Moreover, we derive a short proof for the exact number of

Orthogonal Polynomials With a Semi-Classical Weight and Their Recurrence Coefficients

open access: yesIEEE Access, 2020
Focusing on the weight function $\omega (x,t)=x^{\alpha }e^{-\frac {1}{3}x^{3}+tx}, x\in [0,\infty),\,\,\,\,\alpha >-1,\,\,\,\,t> 0$ , we state its asymptotic orthogonal polynomials.

On the use of Hahn's asymptotic formula and stabilized recurrence for a fast, simple, and stable Chebyshev--Jacobi transform [PDF]

open access: yes, 2016
We describe a fast, simple, and stable transform of Chebyshev expansion coefficients to Jacobi expansion coefficients and its inverse based on the numerical evaluation of Jacobi expansions at the Chebyshev--Lobatto points.
