Nawaz MalikCOMSATS Islamabad PakistanJournal Article20120221In this paper, we introduce a new class$T_{k}^{s,a}[A,B,\alpha ,\beta ]$ of analytic functions by using a
newly defined convolution operator. This class contains many known classes of
analytic and univalent functions as special cases. We derived some
interesting results including inclusion relationships, a radius problem and
sharp coefficient bound for this class.http://bims.iranjournals.ir/article_540_816202a2ed253c9673f8148c1b13bd36.pdf
