520 3 |a Let T be the class of functions f z = z + ∑ n = r ∞ c n z n $$ f(z)=z+{\displaystyle \sum_{n=r}^{\infty }{c}_n{z}^n} $$ regular and typically real in the disk |z| < 1. Sharp estimates for the coefficients c 3 and c 4 in terms of the values f(r), 0 < r < 1, are obtained. Bibliography: 4 titles.
