Initial successive coefficients for certain classes of univalent functions involving the exponential function

Lei Shi, Zhi-Gang Wang, Ren-Li Su +1

Let $\mathcal{S}$ denote the family of all functions that are analytic and univalent in the unit disk $\mathbb{D}:=\{z:|z|<1\}$ and satisfy $f(0)=f^{\prime }(0)-1=0$. In the presen…
