UDC 517.546, 517.57 We study a subclass of harmonic univalent mappings defined by a differential inequality and denoted by $\mathcal{R}_{H}^{0}(\gamma,\delta,\lambda).$ This subclass was introduced in the paper [S. Çakmak, E. Yaşar, S. Yalçin, Hacet. J. Math. Stat., 51, № 1, 172–186 (2022)]. We dete...
