In the present investigation, we introduce and investigate a new subclass of the function class ? of bi-univalent functions defined in the open unit disc. We find estimates on the coefficients |a2| and |a3| for functions in the function class S?(n, h... see more

In the present investigation, we find estimates on the coefficients |a2| and |a3| for functions in the function class S_{S}(?,h). The results presented in this paper improve or generalize the recent work of Magesh and Yamini.

In our present investigation, we use the Faber polynomial expansions to find upper bounds for the n-th (n > =4) coefficients of general subclass of analytic bi-univalent functions. In certain cases, our estimates improve someof those existing coefficie... see more

Recently, the q-derivative operator has been used to investigate several subclasses of analytic functions in different ways with different perspectives by many researchers and their interesting results are too voluminous to discuss. For example, the exten... see more

This paper provides new perturbation bounds for general state Markov chains with respect to various norms. The transition and stationary char- acteristics estimates are given in terms of the generalized norm ergodic- ity coefficient, the norm of a residua... see more

In the present paper, by using the Lp,q,n(x) functions, our methodology intertwine to yield the Theory of Geometric Functions and that of Special Functions, which are usually considered as very different fields. Thus, we aim at introducing a new class of ... see more

The unmanned aerial vehicle dynamic model is identified with the use of combination of two different methods called Estimation before Modeling and Estimation after Modeling, using Kalman filter and available measurements. Tuning of filter is one of the di... see more

In this work, considering a general subclass of bi-univalent Sakaguchi type functions and using Chebyshev polynomials, we obtain coefficient expansions for functions in this class.

In this article we have defined a subclass of Bi-univalent functions using symmetric q- derivative operator and estimated the bounds for the coefficients using Faber polynomial techniques. We also have obtained the bounds for the linear functional which i... see more
