Abstract: |
A function  defined in the domain  is harmonic in  if  ,  are real harmonic. Such functions can be represented as  where  ,  are analytic in  . In this paper the class of harmonic functions constructed by the Hadamard product in unit disk, and properties of some of its subclasses are searched.
