On a New Class of Multivalent Functions With Missing Coefficients

In this paper, we investigate a new class Θ^p,λ_ ε1;ε2 of analytic functions in the open unit disk. By using the geometry function theory, we discuss radius problems between the Θ^p,λ_ ε1;ε2 and the convex functions or close-to-convex functions. Several properties as the sufficient and necessary conditions and modified-Hadamard product are given.
