摘要：
A function f analytic in the unit disk is called a semi-Bloch function if, for each complex number lambda, the function g(lambda)(z) = exp(lambdaf(z)) is a normal function. We give both an analytic and a geometric characterization of semi-Bloch functions, together with some examples to show that semi-Bloch functions are not closed under either addition or multiplication.
