Abstract

The authors established results involving coefficient inequality, extreme points, convolution and

convex combinations using convolution of error and Bessel functions for new class

of harmonic univalent functions in the unit disc.

Keywords: Analytic functions, univalent functions, harmonic function, Bessel function, error function.
