We give sharp bounds for the initial coefficients of the Taylor expansion of such functions in the class of strongly Ozaki close-to-convex functions, and of the initial coefficients of the inverse function, together with some growth estimates.</jats:p> | URI: | http://hdl.handle.net/20.500.12188/884 | DOI: | 10.1017/s0004972718000989 |
