The invariance of strong and almost spirallike mappings of type β and order α
چکیده انگلیسی

The invariance of strong and almost spirallike mappings of type β and order a is discussed in this paper. From the maximum modulus principle of holomorphic functions, we obtain that the generalized Roper-Suffridge operators preserve strong and almost spirallikeness of type β and order α on the unit ball Bn in ℂn and on bounded and complete Reinhardt domains. Therefore we obtain that the generalized Roper-Suffridge operators preserve strong spirallikeness of type β, strong and almost starlikeness of order α, strong starlikeness on the corresponding domains. Thus we can construct more subclasses of spirallike mappings in several complex variables.
