Mathematics, 2020 First, by making use of the concept of basic (or q-) calculus, as well as the principle of subordination between analytic functions, generalization Rq(h) of the class R(h) of analytic functions, which are associated with the leaf-like domain in the open ...

A Note on Meromorphic Functions Associated With Beseel Function Defined by Hilbert Sapce Operator
Concrete Operators, 2021 In this paper,we introduce and study a new subclass of meromorphic functions associated with a certain differential operator on Hilbert space. For this class, we obtain several properties like the coefficient inequality, growth and distortion theorem ...

Argument and Coefficient Estimates for Certain Analytic Functions
Mathematics, 2020 The aim of the present paper is to introduce a new class G α , δ of analytic functions in the open unit disk and to study some properties associated with strong starlikeness and close-to-convexity for the class G α , δ

Coefficient Estimates for a Subclass of Starlike Functions
Mathematics, 2020 In this note, we consider a subclass H3/2(p) of starlike functions f with f″(0)=p for a prescribed p∈[0,2]. Usually, in the study of univalent functions, estimates on the Taylor coefficients, Fekete–Szegö functional or Hankel determinats are given ...

Coefficient estimates for bi-univalent Ma-Minda starlike and convex functions [PDF]
, 2011 Estimates on the initial coefficients are obtained for normalized analytic functions $f$ in the open unit disk with $f$ and its inverse $g=f^{-1}$ satisfying the conditions that $zf'(z)/f(z)$ and $zg'(z)/g(z)$ are both subordinate to a starlike univalent

On estimating the diffusion coefficient [PDF]
Journal of Applied Probability, 1987 Random processes of the diffusion type have the property that microscopic fluctuations of the trajectory make possible the identification of certain statistical parameters from one continuous observation. The paper deals with the construction of parameter estimates when observations are made at discrete but very dense time points.

Explicit estimates for solutions of mixed elliptic problems [PDF]
, 2013 We deal with the existence of quantitative estimates for solutions of mixed problems to an elliptic second order equation in divergence form with discontinuous coefficient. Our concern is to estimate the solutions with explicit constants, for domains in $

Cross-imaging system comparison of backscatter coefficient estimates from a tissue-mimicking material. [PDF]
J Acoust Soc Am, 2012 A key step toward implementing quantitative ultrasound techniques in a clinical setting is demonstrating that parameters such as the ultrasonic backscatter coefficient (BSC) can be accurately estimated independent of the clinical imaging system used.

Maclaurin Coefficient Estimates of Bi-Univalent Functions Connected with the q-Derivative
, 2020 In this paper we introduce a new subclass of the bi-univalent functions defined in the open unit disc and connected with a q-analogue derivative. We find estimates for the first two Taylor-Maclaurin coefficients a 2 and a 3 for functions in this subclass,
