In this paper, we introduced new subclasses UCVs(α,β) and SPs(α,β) which are sub classes of UCV (α,β) and SP(α,β) and studied the T - δ neighbourhoods of functions in these classes. The results obtained in this paper generalizes the recent results of Parvatham and Premabai, Ram Reddy and Thirupathi Reddy, Padmanabhan, and Ronning.
