Univalence Criteria for Two Integral Operators
Abstract and Applied Analysis, 2012 We study the univalence conditions for two integral operators to be univalent in the open unit disk. Many known univalence conditions are written to prove our main results.

Indefinite structure of the Bergman kernel on the open unit disk
Journal of Mathematical Analysis and ApplicationsIn this paper, we focus on an indefinite structure lying behind the Bergman kernel on the open unit disk. In particular, an invariant distance, birational maps and an indefinite kernel are constructed from the Bergman kernel, and we deal with their interaction.

Upper Cervical Cord Area as a Biomarker of Conversion to Secondary Progressive Multiple Sclerosis
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective This study assessed whether upper cervical cord area (UCCA) measured on routine brain MRI can serve as a biomarker of conversion to SPMS. Methods This is a single‐center retrospective cohort study of RRMS patients with cross‐sectional and longitudinal analyses of clinical and MRI data. Future SPMS converters were matched by age, sex,

New criteria for Carathéodory functions
Journal of Inequalities and Applications, 2019 The object of the present paper is to investigate various conditions for Carathéodory functions in the open unit disk. Also we give some applications to univalent functions as special cases.

Starlikeness Properties of a New Integral Operator for Meromorphic Functions
Journal of Applied Mathematics, 2011 We define here an integral operator ℋ𝛾1,…,𝛾𝑛 for meromorphic functions in the punctured open unit disk. Several starlikeness conditions for the integral operator ℋ𝛾1,…,𝛾𝑛 are derived.
