This newly defined class is a subclass of class A of normalized analytic functions, where class A is invariant (or symmetric) under rotations. For this function class we obtain an upper bound of the third Hankel determinant.enstarlike functionssubordinationq-Differential operatork-Fibonacci numbersArticleDepartment of Mathematics and Statistics
