We introduce the subclass Tj (n, m, γ, α, λ) of analytic functions with negative coefficients defined by generalized Salagean operator Dn λ. Coefficient estimates, some important …
Making use of Salagean operators, Dn and Dn+ m (n∈ N0= N∪{0}, m∈ N={1, 2,...}), we define the class Tj (n, m, α, β)(n∈ N0, j, m∈ N,− 1≤ α< 1, β≥ 0). In this paper, we obtain …
