Inclusion properties for certain classes of differential subordination
In this work, we introduce a new generalised derivatives operator µ n,m. By using this operator, we introduce several new subclasses of analytic function defined in the open unit disc U = {z € C:|z|<1}. We also investigate various inclusion properties of these subclasses. In addition, we deter...

| Summary: | In this work, we introduce a new generalised derivatives operator µ n,m. By using this
operator, we introduce several new subclasses of analytic function defined in the open unit
disc U = {z € C:|z|<1}. We also investigate various inclusion properties of these
subclasses. In addition, we determine inclusion relationships between these new subclasses
and other known classes.
