Uniqueness on the Class of Odd-Dimensional Starlike Obstacles with Cross Section Data [PDF]

, 2010
We determine the uniqueness on starlike obstacles by using the cross section data. We see cross section data as spectral measure in polar coordinate at far field. Cross section scattering data suffice to give the local behavior of the wave trace.

Coefficient Bounds for Certain Classes of Meromorphic Functions

Journal of Inequalities and Applications, 2009
Sharp bounds for |a1−μa02| are derived for certain classes Σ∗(ϕ) and Σα∗(ϕ) of meromorphic functions f(z) defined on the punctured open unit disk for which −zf′(z)/f(z) and (−(1−2α)zf′(z)+Π...

Partial Sums of Certain Classes of Meromorphic Functions Related to the Hurwitz-Lerch Zeta Function

Moroccan Journal of Pure and Applied Analysis, 2015
In the present paper, we give sufficient conditions for a function f to be in the subclasses ΣS*a,s (A. B, α, β) and ΣKa,s (A, B, α, β) of the class Σ of meromorphic functions which are analytic in the punctured unit disk U*.

On p-Valently Meromorphic-Strongly Starlike and Convex Functions

International Journal of Analysis and Applications, 2016
In this paper, we obtain sufficient conditions for analytic function $f(z)$ in the punctured unit disk to be $p$-valently meromorphic-strongly starlike and $p$-valently meromorphic-strongly convex of order $\beta$ and type $\alpha$.
