摘要：

In the present paper we establish several strong differential subOrdinntions regardind the operator I (m, lambda, l), given by I (m, lambda, l) : A(n zeta)(*) -> A(n zeta)(*), I (m, lambda, l) f (z, zeta) := z + Sigma(infinity)(j=n+1) (1+lambda(j-1)+l/l+1)(m) a(j) (zeta) z(j), where m is an element of N boolean OR {0}, lambda, l >= 0 and A(n zeta)(*) = {f is an element of H(U x (U) over bar), f(z, zeta) = z + a(n+1) (zeta) z(n+1) + ..., z is an element of U, zeta is an element of (U) over bar} is the class of normalized analytic functions.
