In our previous work in this journal in 2008, we introduced the generalized derivative operator Open image in new window for Open image in new window . In this paper, we introduce a class of meromorphic harmonic function with respect to Open image in new window -symmetric points defined by Open image in new window . Coefficient bounds, distortion theorems, extreme points, convolution conditions, and convex combinations for the functions belonging to this class are obtained.
