Second Hankel detreminant problem for some analytic function classes with connected k-fibonacci numbers

OpenAlex İngilizce

In this paper, we determine upper bound for the second Hankel determinant in some classes of analytic functions in the open unit disc connected with k-Fibonacci numbers F k,n (k > 0).For this purpose we apply properties of k-Fibonacci numbers to consider second Hankel determinant problem for the class SL k and KSL k .The results presented in this paper have been shown to generalize and improve some recent work of Sokó l et al. [18].
