Abstract
In this paper, we investigate holomorphic mappings $F$ on the unit ball
$\mathbb{B}$ of a complex Banach space of the form $F(x)=f(x)x$, where $f$ is a
holomorphic function on $\mathbb{B}$. First, we investigate criteria for
univalence, starlikeness and quasi-convexity of type $B$ on $\mathbb{B}$. Next,
we investigate a generalized Bieberbach conjecture, a covering theorem and a
distortion theorem, the Fekete-Szeg\"{o} inequality, lower bound for the Bloch
constant, and Alexander's type theorem for such mappings.
