Univalency and convolution results associated with confluent hypergeometric functions
(Houston Journal of Mathematics, 2009)
Given the confluent hypergeometric functions Φ(a; c; z), we
place conditions on a and c to guarantee that zΦ(a; c; z) will be in two sub-
classes of univalent functions. In addition, we obtain conditions to obtain
some ...

Starlikeness of sections of univalent functions
(Rocky Mountain Mathematics Consortium, 2014)
Let S be the class of all normalized analytic
and univalent functions in the unit disk D. In this paper, we
determine condition so that each section sn(f, z) of f ∈ S is
starlike in the disk |z| < rn. In particular, ...
