Abstract:

In this thesis, with the properties of Loewner chains,  the upper bound of second order item coefficients of homogeneous expansion for spirallike mappings relative to A was obtained via the characters of spirallike mappings relative to A on the unit ball Bn in Cn.

Key words: Normal starlike mappings, Spirallike mappings relative to A, Estimation of homogeneous expansion
