An asymptotic formula for the number of non-negative integer matrices with prescribed row and column sums [PDF]
, 2009 We count mxn non-negative integer matrices (contingency tables) with prescribed row and column sums (margins). For a wide class of smooth margins we establish a computationally efficient asymptotic formula approximating the number of matrices within a ...

Asymptotic Normality in Linear Regression with Approximately Sparse Structure
Mathematics, 2022 In this paper, we study the asymptotic normality in high-dimensional linear regression. We focus on the case where the covariance matrix of the regression variables has a KMS structure, in asymptotic settings where the number of predictors, p, is ...

Quaternionic Artin representations of Q [PDF]
, 2016 Isomorphism classes of dihedral Artin representations of ℚ can be counted asymptotically using Siegel's asymptotic averages of class numbers of binary quadratic forms. Here we consider the analogous problem for quaternionic representations.

A hybrid asymptotic formula for the second moment of Rankin–Selberg L‐functions [PDF]
, 2010 Let g be a fixed modular form of full level, and let {fj, k} be a basis of holomorphic cuspidal newforms of even weight k, fixed level and fixed primitive nebentypus.

Asymptotic formula in simultaneous approximation for certain Ismail-May-Baskakov operators
Journal of Numerical Analysis and Approximation Theory, 2021 In the present paper, we introduce a modification of Ismail-May operators having weights of Baskakov basis functions. We estimate weighted Korovkin's theorem and difference estimates between two operators and establish a Voronovskaja type asymptotic ...

On Optimal and Asymptotic Properties of a Fuzzy L2 Estimator
Mathematics, 2020 A fuzzy least squares estimator in the multiple with fuzzy-input–fuzzy-output linear regression model is considered. The paper provides a formula for the L2 estimator of the fuzzy regression model. This paper proposes several operations for fuzzy numbers

Zamolodchikov asymptotic formula and instanton expansion in = 2 SUSY Nf = 2Nc QCD [PDF]
, 2009 The AGT relations allow to convert the Zamolodchikov asymptotic formula for conformal block into the instanton expansion of the Seiberg-Witten prepotential for the theory with two colors and four fundamental flavors. This provides an explicit formula for

On the Asymptotic Formula of a Bessel’s Functions Product in Intermodulation Analysis
Tongxin xuebao, 1984 A probability proof of an asymptotic formula of Bessel’s functions product is given. The asymptotic formula, while used for intermodulation analysis, would save a lot of computing time.

Axioms, 2020 An asymptotic solution of the linear Cauchy problem in the presence of a “weak” turning point for the limit operator is constructed by the method of S. A. Lomov regularization. The main singularities of this problem are written out explicitly.

Semiclassical Analysis of the Wigner $12j$ Symbol with One Small Angular Momentum
, 2011 We derive an asymptotic formula for the Wigner $12j$ symbol, in the limit of one small and 11 large angular momenta. There are two kinds of asymptotic formulas for the $12j$ symbol with one small angular momentum.
