An Application of Fuzzy Multiple Linear Regression in Biological Paradigm

open access: yesComplexity, 2022
The regression model is generally utilized in several fields of study because of its applications. Regression is an extremely incredible approach; it builds up a connection between dependent and independent variables.

Univalence Criteria for some General Integral Operators

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2021
The main object of this paper is to extend the univalent condition for two general integral operators. A number of known univalent condition would follow upon specializing the parameters involved in our main results.

Estimate for Initial MacLaurin Coefficients of Certain Subclasses of Bi-univalent Functions [PDF]

open access: yes, 2015
In this paper, estimates for second and third MacLaurin coefficients of certain subclasses of bi-univalent functions in the open unit disk defined by convolution are determined, and certain special cases are also indicated.

On a local version of Jack’s lemma

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2019
The purpose of this paper is to provide a result which concerns with the boundary behavior of analytic functions. It may be a local version of the well known Jack’s lemma when we change the function normalization at the origin.

Coefficient estimates of new classes of q-starlike and q-convex functions of complex order

open access: yes, 2016
We introduce new classes of q -starlike and q -convex functions of complex order involving the q -derivative operator defined in the open unit disc. Furthermore, we find estimates on the coefficients for second and third coefficients of these classes ...

The Relationships Between p−valent Functions and Univalent Functions

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2015
In this paper, we obtain some sufficient conditions for general p−valent integral operators to be the p−th power of a univalent functions in the open unit disk.

The Fekete-Szegö functional problems for some subclasses of m-fold symmetric bi-univalent functions

open access: yes, 2016
In this paper, we introduce several new subclasses of the class of m -fold symmetric bi-univalent functions and obtain estimates of the Taylor-Maclaurin coefficients |am+1| , |a2m+1| and Fekete-Szegö functional problems for functions in these new ...
