Our investigation extends to the analysis of coefficient bounds, growth estimates, starlikeness, and convexity radii uniquely associated with this particular class. Furthermore, we scrutinize the property of closure under convolution operations for this subclass.eninfo:eu-repo/semantics/openAccessharmonic multivalent functionscoefficient boundsdistortion theoremstarlikeness radiiconvexity radiiconvolutionArticle54256257410.15672/hujms.1428478Q2001481894500015Q2
