Differential subordination for certain generalized operator
M. H. Al-Abbadi; M. Darus;Abstract
The authors have recently introduced a new generalised derivatives operator
μn,m
1,2
, which generalised many well-known operators studied earlier by many
different authors. The trend of finding new operators such as the differential or
the integral operators has attracted many researchers and in fact, has become
necessary to some of the researchers. The aim of this paper is to use the
equality relation
(1 + n) μn+1,m
1,2
f(z) = z
