摘要：

This paper looks at subordination properties involving 1+beta zp' (z) and the class of Sokol-Stankiewicz starlike functions where condition on beta is determined so that the relation 1 + beta zp' (z) < root 1 + cz would imply p(z) < root 1 + z. Similar results are obtained for expressions of the form 1 + beta zp'(z)/p(z) and 1 + beta zp' (z)/p(2)(z). These results are then applied to obtain other relations involving similar expressions.
