An analytical function class N(α,μ,A,B) is introduced.By using the extremum of function and monotonicity,the sharp upper bounds of  |a3-μa22|  for any complex parameter are discussed,which generalize some existing results.

Key words: univalent function;non-Bazilevicˇ function;N(α, μ, A, B) function;Fekete-Szegeg , inequality
