For certain analytic functions f(z) in the open unit disk U, two subclasses P(alpha, delta; g) and Q(alpha, delta; g) associated with some analytic function g(z). Some interesting sufficient conditions for f (z) to be in T(alpha, delta; g) and Q(alpha, delta; g) and some necessary conditions for f (z) belonging to P(alpha, delta; g) and Q(alpha, delta; g) are considered.
