| Summary: | In this work, a class of meromorphic harmonic concave functions defined by Oboudi operator in
the punctured unit disc is introduced. Coefficient conditions, distortion inequalities, extreme
points, convolution bounds, geometric convolution, integral convolution and convex
combinations for functions f belonging to this class are obtained. |
