Abstract

In this paper, we investigate a generalized family of complex-valued harmonic functions that are multivalent, sense-preserving, and are associated with $k$-uniformly harmonic functions in the unit disk. The results obtained here include a number of known and new results as their special cases.

Keywords: harmonic functions, multivalent harmonic functions, convex combinations, distortion bounds, uniformly harmonic starlike
