Bi- Starlike function of complex order involving Rabotnov function subordinated to Lucas Balancing polynomial

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
Considering the interesting results obtained recently by studying Rabotnov function, in this paper using the normalized Rabotnov function and the concept of subordination related with the Lucas Balancing polynomial, we defined two new subclasses of the ...

On a subclass of p-valent analytic functions involving fractional q-calculus operators

open access: yesKuwait Journal of Science, 2015
In this paper, we consider a new subclass of p-valent analytic functions in the open unitdisk involving a fractional q-differeintegral operator. For this subclass of functions,we derive the coefficient inequality and some distortion theorems.

Bounds for Exponential Sums With Random Multiplicative Coefficients

open access: yesInternational Mathematics Research Notices
Abstract For $f$ a Rademacher or Steinhaus random multiplicative function, we prove that $ \max _{\theta \in [0,1]} \frac{1}{\sqrt{N}} \bigl | \sum _{n \leq N} f(n) \mathrm{e} (n \theta ) \bigr | \gg \sqrt{\log N}$, asymptotically almost surely as $N \rightarrow \infty $.

Coefficient bounds for p-valent functions

Applied Mathematics and Computation, 2007
Sharp bounds for \(|a_{p+2}-\mu a^2_{p+1}|\) and \(|a_{p+3}|\) and \(|a_{p+3}|\) are derived for certain \(p\)-valent analytic functions. These are applied to obtain Fekete-Szegő like inequalities for several classes of functions defined by convolution.

Bounds on Texture Coefficients

Journal of Applied Mechanics, 2003
The orientation distribution function (ODF) is expanded in terms of generalized spherical harmonics and bounds on the resulting texture coefficients are derived. A necessary and sufficient condition for satisfaction of the normalization property of the ODF is also provided. These results are of significance in, for example, microstructural optimization

NORMAL FUNCTIONS WITH BOUNDED COEFFICIENTS

Analysis, 1983
In an earlier work [Proc. Am. Math. Soc. 85, 335-341 (1982; Zbl 0492.30025)] the author had proven that if \(\{a_ n\}\) is a bounded monotone sequence of real numbers, or if \(\sum | a_ n-a_{n-1}|
