摘要：

The aim of this paper is to determine sharp bound for the second Hankel determinant of logarithmic coefficients H-2,H-1(F-f/2) of strongly Ozaki close-to-convex functions in the open unit disk. Furthermore, sharp bound of H-2,H-1(F-f-1/2), where f(-1) is the inverse function of f, is also computed. The results show an invariance property of the second Hankel determinants of logarithmic coefficients H-2,H-1(F-f/2) and H-2,H-1(F-f-1/2) for strongly convex functions.
