摘要：

Let U+ be the class of analytic functions f such that z / f(z) has real and positive coefficients and f(-1) be its inverse. In this paper we give sharp estimates of the initial coefficients and initial logarithmic coefficients for f, as well as, sharp estimates of the second and the third Hankel determinant for f and f(-1). We also show that the Zalcman conjecture holds for functions f from U+.
