Meromorphically Starlike Functions at Infinity

, 2020
In this letter, we introduce meromorphically starlike functions by using a particular class of analytic functions that present authors applied in 2012 [cf.[1]]. These functions map the punctured unit disk into a starlike domain at infinity.

Some characterizations of univalent, starlike and convex hypergeometric functions [PDF]

, 2010
E.P. Merkes and W.T. Scott [Proc. Amer. Math. Soc. 12(1961), 885-888] proved an interesting result characterizing starlike hypergeometric functions. More recently, B.C. Carlson and D.B. Shaffer [SIAM J. Math. Anal.

Applications of q-Bessel-Struve Functions on Univalent Functions

Mathematics
In this paper, the authors derived some new sufficient conditions for q-close-to-convexity with respect to certain functions involving three different normalizations of q-Bessel–Struve functions.

Computation of eigenvalues for starlike domains

, 1994
In this paper, we present a software tool for the computation of eigenvalues of starlike domains defined by polar boundary functions. We also offer and numerically test a conjecture on the monotonicity of the fundamental eigenvalues of the members of a ...

On the Gakhov Equation for the Biernacki Operator [PDF]

Учёные записки Казанского университета: Серия Физико-математические науки, 2015
The paper establishes the region in the parameter plane such that the image of any starlike function with the zero root of the Gakhov equation under the mapping by the Biernacki operator corresponding to the parameter of this region is found in the ...
