چکیده
|
In this paper, we investigate an interesting subclass of uni- valent functions. also, we introduce a new subclass of meromorphic bi-univalent functions. we obtain the estimates on the initial taylor- maclurin coecients for functions in the interesting subclass of meromor- phically bi-univalent functions de ned on δ = {z ∈ c : 1 < │z│ < ∞ }
