"Fourth Hankel determinant for a subclass of analytic functions defined by generalized Sălăgean operator"

Abstract

" This paper is concerned with the estimation of fourth Hankel determinant for a subclass of analytic functions defined by generalized S\~{a}l\~{a}gean operator in the open unit disc $E=\{z: |z|<1\}$. The present study sets the stage for other researchers to investigate the fourth Hankel determinant for some other subclasses of analytic functions."
