Convolution properties of Salagean-type harmonic univalent functions

2011
Jahangiri et al. [5] defined "modified Salagean operator" for harmonic univalent functions in the unit disk. In that study, they also obtained necessary and sufficient coefficient conditions for the Salagean-type class of harmonic univalent functions.

Stability of geometric properties of convolutions of univalent harmonic functions

1996
For given subclasses \(M\), \(N\), \(P\) of a class of complex-valued harmonic functions, the author defines the notion of stability of the convolution \(M*N\) with respect to \(P\). Then, some stability theorems are proved for the Hadamard convolution and the integral convolution as defined in \textit{Y. Avci} and \textit{E. Złotkiewicz} [Ann.
