MHD Flow due to the Nonlinear Stretching of a Porous Sheet
Advances in Mathematical Physics, 2016 The MHD flow due to the nonlinear stretching of a porous sheet is investigated. A closed form solution is obtained when the stretching rate is inversely proportional to the distance from the origin.

Integral Representation and Asymptotic Expansion for Hypergeometric Coherent States
Mathematics, 2022 An integral representation is found for hypergeometric coherent states. It contains a generalized hypergeometric function. An asymptotic expansion of hypergeometric coherent states near z=1 is constructed.

Journal of Mathematical Analysis and Applications, 1996 Let \(\{V_n\}\) be a sequence of vector spaces with \(V_{n + 1} \subseteq V_n\) for \(n = 0,1,2, \dots\). A series \(\sum^\infty_{n = 0} v_n\) with \(v_n \in V_n\) is called a pre-asymptotic expansion of \(v \in V_0\), written \(v \sim \sum^\infty_{n = 0} v_n\) with respect to \(\{V_n\}\), if \(v - \sum^N_{n = 0} v_n \in V_{N + 1}\) for all \(N ...

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.

An asymptotic expansion for a ratio of products of gamma functions
International Journal of Mathematics and Mathematical Sciences, 2000 An asymptotic expansion of a ratio of products of gamma functions is derived. It generalizes a formula which was stated by Dingle, first proved by Paris, and recently reconsidered by ...

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 ...
