“…Cho et al [3] established some inclusion relationships and argument properties for certain subclasses of A p , which were defined in terms of their operator I λ p (a, c)(see also [18]). For the choices λ = c = 1 and a = n + p, the Cho-Kwon-Srivastava operator I λ p (a, c) reduces to the operator I 1 p (n + p, 1) = I n,p (n > −p), where I n,p is the integral operator studied by Liu and Noor [9](for details, see [10] and [11]).…”
