Coefficient estimates for Ruscheweyh derivatives
We consider functions f, analytic in the unit disc and of the normalized form f(z)=z+∑n=2∞anzn. For functions f∈R¯δ(β), the class of functions involving the Ruscheweyh derivatives operator, we give sharp upper bounds for the Fekete-Szegö functional |a3 ...

Coefficient estimates for families of bi-univalent functions defined by Ruscheweyh derivative operator [PDF]
The main purpose of this manuscript is to find upper bounds for the second and third Taylor-Maclaurin coefficients for two families of holomorphic and bi-univalent functions associated with Ruscheweyh derivative operator.

Estimating Coefficient Distributions in Random Coefficient Regressions
The model is \(Y_ j=a+(b+j)x_ j+e_ j\), \(j=1,2,\dots\) where \(E(b_ j)=E(e_ j)=0\), the \(b_ 1,e_ 1,b_ 2,e_ 2,\dots\) are independent and \(\{b_ 1,b_ 2,\dots\}\) as well as \(\{e_ 1,e_ 2,\dots\}\) are i.i.d. The authors study the estimation of the distribution of \(b_ j\) and \(e_ j\), respectively, for resampling purposes.

Stability estimates for a Robin coefficient in the two-dimensional Stokes system [PDF]
In this paper, we consider the Stokes equations and we are concerned with the inverse problem of identifying a Robin coefficient on some non accessible part of the boundary from available data on the other part of the boundary.

In this article, we derive some estimates for the Taylor-Maclaurin coefficients of functions that belong to a new general subclass $ \Upsilon_\Sigma(\delta, \rho, \tau, n;\varphi) $ of bi-univalent functions in an open unit disk, which is defined by ...

Here in our paper, we present two new subclasses of multivalent analytic functions and complex order by using q–p-valent Cătaş operator. Also we obtain coefficient estimates and consequent inclusion relationships involving the $N_{i,\delta }^{\mathbf {p}

The results presented in this paper deal with the classical but still prevalent problem of introducing new classes of m-fold symmetric bi-univalent functions and studying properties related to coefficient estimates.

On Coefficient Estimates for a Certain Class of Analytic Functions
In this paper, we consider a subclass SQ of normalized analytic functions f satisfying ℜf′(z)>1/2. For the functions in the class SQ, we determine upper bounds for a number of coefficient estimates, among which are initial coefficients, the second Hankel
