Shrinking Starlike Sets

2021
Abstract ‘Shrinking Starlike Sets’ presents a proof that null decompositions with recursively starlike-equivalent elements shrink. Unlike in previous chapters, the shrink is produced abstractly rather than explicitly. The chapter proceeds in steps, first establishing the shrinking of null decompositions with starlike elements, then of ...

Characterization of Transmission Irregular Starlike and Double Starlike Trees

Computational and Applied Mathematics
The transmission of a vertex in a connected graph is the sum of its distances to all the other vertices. A graph is transmission irregular (TI) when all of its vertices have mutually distinct transmissions. In an earlier paper, Al-Yakoob and Stevanović [Appl. Math. Comput.

Some General Classes of q-Starlike Functions Associated With the Janowski Functions [PDF]

Symmetry, 2019
By making use of the concept of basic (or q-) calculus, various families of q-extensions of starlike functions of order α in the open unit disk U were introduced and studied from many different viewpoints and perspectives. In this paper,

Certain Results on Starlike and Parabolic Starlike Functions

International Journal of Open Problems in Computer Science and Mathematics, 2015
Using the technique of differential subordination, we obtain certain results for starlike and parabolic starlike functions involving the differential operator zf ′(z) f(z) ( 1 + α zf ′′(z) f ′(z) ) . We study the above operator for multivalent functions and also conclude some results for univalent functions.

Simple criterions for strongly starlikeness and starlikeness of certain order

Mathematische Nachrichten, 2003
AbstractIn this paper, we will give a sufficient condition for locally univalent holomorphic functions on the unit disc . in C to be strongly starlike. Also, we will give sufficient conditions for locally biholomorphic mappings on the unit ball B in a complex Banach space X to be starlike of certain order or strongly starlike.

Sufficient Conditions for Starlikeness and Strong-starlikeness of a Given Order

Complex Variables, Theory and Application: An International Journal, 2003
We find sharp upper bounds for $ \vert \,f^{\prime \prime }(z)/f^{\prime }(z) \vert $ such that the function f be starlike or strongly-starlike of a given order, where f is holomorphic in the unit disc U , with $ f(0)=f^{\prime }(0)-1=0 $ . These bounds are obtained by using the differential subordination technique. As a useful ingredient we obtain the
