Black Hole Entropy Associated with Supersymmetric Sigma Model [PDF]
, 2003 By means of an identity that equates elliptic genus partition function of a supersymmetric sigma model on the $N$-fold symmetric product $S^N X$ of $X$ ($S^N X=X^N/S_N$, $S_N$ is the symmetric group of $N$ elements) to the partition function of a second ...

An Alternative Approach to Energy Eigenvalue Problems of Anharmonic Potentials
Advances in Mathematical Physics, 2014 Energy eigenvalues of quartic and sextic type anharmonic potentials are obtained by using an alternative method called asymptotic Taylor expansion method (ATEM) which is an approximate approach based on the asymptotic Taylor series expansion of a ...

Advances in Difference Equations, 2020 The step-type contrast structure for a second order semi-linear singularly perturbed differential-difference equation is studied. Using the methods of boundary function and fractional steps, we construct the formula asymptotic expansion of the problem ...

Bessel function expansions of Coulomb wave functions [PDF]
, 1985 From the convergence properties of the expansion of the function Φ_l∝r^(−l−1)F_l in powers of the energy, we successively obtain the expansions of F_l and G_l as single series of modified Bessel functions I_(2l+1+n) and K_(2l+1+n), respectively, as well ...

Random normal matrices, Bergman kernel and projective embeddings [PDF]
, 2014 We investigate the analogy between the large N expansion in normal matrix models and the asymptotic expansion of the determinant of the Hilb map, appearing in the study of critical metrics on complex manifolds via projective embeddings.

Regularization and asymptotic expansion of certain distributions defined by divergent series
International Journal of Mathematics and Mathematical Sciences, 1995 The regularization of the distribution ∑n=−∞∞δ(x−pn). which gives a regularized value to the divergent series ∑n=−∞∞φ(pn) is obtained in several spaces of test functions. The asymptotic expansion as ϵ→0+of series of the type ∑n=0∞φ(ϵ pn) is also obtained.

On the Sharp Gårding Inequality for Operators with Polynomially Bounded and Gevrey Regular Symbols
Mathematics, 2020 In this paper, we analyze the Friedrichs part of an operator with polynomially bounded symbol. Namely, we derive a precise expression of its asymptotic expansion.

Determinants of Laplacians on discretizations of flat surfaces and analytic torsion
Comptes Rendus. Mathématique, 2020 We study the asymptotic expansion of the determinants of the graph Laplacians associated to discretizations of a half-translation surface endowed with a unitary flat vector bundle. By doing so, over the discretizations, we relate the asymptotic expansion

Condensed Matter Physics, 2014 We analyze the resistance between two nodes in a cobweb network of resistors. Based on an exact expression, we derive the asymptotic expansions for the resistance between the center node and a node on the boundary of the M x N cobweb network with ...

Asymptotic expansion in approximation by normal law
Lietuvos Matematikos Rinkinys, 2011 We consider the asymptotic behavior of the convolution P*n(A\sqrt{n}) of a k-dimensional probability distribution P(A) as n \to \infty for A from the \sigma-algebra M of Borel subsets of Euclidian space Rk or from its subclasses.
