ABSTRACT
Motivated and
stimulated especially by the work of Xu et
al. [1], in this paper, we introduce and discuss an
interesting subclass 
of
analytic and bi-univalent functions defined in the open unit disc U. Further, we find estimates on the
coefficients 
and 
for
functions in this subclass. Many relevant connections with known or new results
are pointed out.
