Özet

Using a Hilbert space operator, we define a new subclass of analytic functions defined by p-valent q-Sălăgean operator and determine coefficient estimates, distortion bounds, radii of close-to-convexity, starlikeness, and convexity for the functions in this class. We also investigate extreme points and the modified Hadamard product.
