Reciprocal classes of p -valently spirallike and p -valently Robertson functions

摘要

For p-valently spirallike and p-valently Robertson functions in the open unit disk U , reciprocal classes S p ( α , β ) , and C p ( α , β ) are introduced. The object of the present paper is to discuss some interesting properties for functions f(z) belonging to the classes S p ( α , β ) and C p ( α , β ) . 2010 Mathematics Subject Classification Primary 30C45
