Convex and starlike criteria [PDF]

International Journal of Mathematics and Mathematical Sciences, 1999
We investigate an expression involving the quotient of the analytic representations of convex and starlike functions. Sufficient conditions are found for functions to be starlike of a positive order and convex.

Hankel and Toeplitz Determinants for q-Starlike Functions Involving a q-Analog Integral Operator and q-Exponential Function

Journal of Function Spaces
This article investigates the upper bounds of the second Hankel and Toeplitz determinants for a family of q-starlike functions defined by a q-analog integral operator, which is a more general form of the q-Srivastava-Attiya operator, and the q ...

The coefficients of starlike functions [PDF]

Proceedings of the American Mathematical Society, 1969
disc. The proof of the local maximum theory for the coefficients of univalent functions by Bombieri [2] and by Garabedian and Schiffer [3] gives strength to the conjecture that these dn exist, but no estimate of their size is available from these papers.

On the Coefficients of Starlike Functions [PDF]

Proceedings of the American Mathematical Society, 1972
Every probability measure μ \mu on the circle group generates a function f that is starlike univalent on the open unit disc Δ \Delta . In this note the relationship between ( c n ) ({c_n}) , the Fourier-Stieltjes coefficients of

Integral starlike trees [PDF]

Journal of the Australian Mathematical Society, 1979
AbstractIn this note we determine which of the trees homeomorphic to a star have a spectrum consisting entirely of integers. We also specify the integral double stars, and we consider the problem of trees with more complicated structure.Subject classification (Amer. Math. Soc. (MOS) 1970): 05 C 05.

SOME CRITERIA FOR STARLIKENESS AND STRONGLY STARLIKENESS [PDF]

Bulletin of the Korean Mathematical Society, 2005
The authors discuss on certain sufficient conditions for starlikeness and strongly starlikeness of analytic functions in the unit disk. Their results generalise and refine known results of \textit{J.-L. Li} and \textit{S. Owa} [Indian J. Pure Math. 33, 313--318 (2002; Zbl 0998.30010), Georgian Math. J. 5, 361--366 (1998; Zbl 0924.30008)] and of \textit{
