SCHWARZ’S DERIVATIVE AND THE UNIVALENCE OF FUNCTIONS
【摘要】 <正> Let f(z) be a meromorphie function on the unit disk D: |z|<1. The Schwarz’s derivative of f(z) is defined as S_f= (f″/f′)′ - (1/2) (f″/f′)~2. Suppose that S_f is holomorphic in D throughout the present note. London had studied the problem of
