Differential superordination for harmonic complex-valued functions

Georgia Irina Oros, Gheorghe Oros


In a previously published paper,in 2015, S. Kanas introduced the differential subordination for harmonic complex-valued functions. In this article,we introduce the dual notion of differential superordination for harmonic complex-valued functions.


Differential subordination for complex-valued harmonic functions; differential superordination for complex valued harmonic functions; subordinant; best subordinant.
