摘要：

Let P0 H ( M) denote the class of normalised harmonic mappings f = h + g in the unit disk D satisfying Re (zh00(z)) > M + jzg00(z) j, where h0 (0) 1 = 0 = g0(0) and M > 0. Let B0 H (M) denote the class of sense-preserving harmonic mappings f = h + g in the unit disk D satisfying jzh00 (z) j M jzg00 (z) j, where M > 0. We discuss the coe fficient bound problem, the growth theorem for functions in the class P0 H (M) and a two-point distortion property for functions in the class B-H(0) (M).
