Sufficient conditions for λ - spirallike and λ - robertson functions of complex order
One of the additions to the fundamental results of the geometric theory of multidimensional complex analysis on the problems of classes of holomorphic functions is considered. The surprising use of special function classes has sparked new interest in function theory in the past few decades.We defined and proved sufficient conditions for a family of class λ - Spirallike and λ - Robertson functions (|λ |<π /2 ) of complex order b∈ C * :=C\ 0 and type α ,0≤α <1 , in complete bounded multiples of circular domains D ⊂ C n . Some classes and subclasses of holomorphic λ - Spirallike and λ - Robertson functions of complex order of functions of many complex variables are defined.
