On α-convex functions of order β with m-fold symmetry
This note is a continuation of the previous work [1,2,3]. First we get a new subordination for α-convex functions of order β when α=1−2β, which implies the rotation theorem for (1−2β)/m-convex functions of order β with m-fold symmetry. Then we extend the known results on α-convex functions of order...
