Let f be a normalized analytic function in the open unit disk of the complex plane satisfying zf'(z)/f(z) is subordinate to a given analytic function ?. A sharp bound is obtained for the second Hankel determinant of the kth-root transform z[f(zk)/zk]1/k. Best bounds for the Hankel determinant are also derived for the kth-root transform of several other classes, which include the class of ?-convex functions and ?-logarithmically convex functions. These bounds are expressed in terms of the coefficients of the given function ?, and thus connect with earlier known results for particular choices of ?.

The purpose of this paper is to establish some refinements of Riemann-Liouville fractional Hermite-Hadamard inequalities for (?,m)-logarithmically convex functions. By using our fractional integrals identities, we present some interesting and new left type fractional Hermite-Hadamard inequalities for once and twice differentiable (?,m)-logarithmically convex functions via powerful series.

If f(z) is a non-constant, entire function, then Hadamard's three-circles theorem asserts thatis a convex, increasing function of log r. Hence, by well-known properties of logarithmically convex functions,

In this paper, the authors establish some new Hadamard type inequalities for s-logarithmically convex functions in the second sense via fractional integrals by using Lemma 1.1 which has been proved by Sarıkaya et al.
