Growth theorems and coefficient bounds for g-starlike mappings of complex order λ

Open Mathematics
Let f be a g-starlike mapping of complex order λ such that x = 0 is a zero of order k + 1 of f(x) − x. By utilizing the geometric properties of f, we characterize its growth theorems and coefficient bounds.

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

Kuwait 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.

Hankel determinants for q-starlike functions connected with q-sine function

Demonstratio Mathematica
This article comprises the study of a new class of starlike functions, which is defined by qq-fractional operator and subordination to the qq-analog of sine function.

Bounds for Exponential Sums With Random Multiplicative Coefficients

International 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 $.
