摘要：

For f analytic in the unit disk D, we consider the close-to-convex analogue of a class of starlike functions introduced by R. Singh ['On a class of star-like functions', Compos. Math. 19(1) (1968), 78-82]. This class of functions is defined by vertical bar zf'(z)/g(z) - 1 vertical bar < 1 for z is an element of D, where g is starlike in D. Coefficient and other results are obtained for this class of functions.
