The second Hankel determinant of logarithmic coefficients and logarithmic inverse coefficients for the class of bounded turning functions of order α. Lithuanian Mathematical Journal, 1-16.0363-16721573-8825https://doi.org/10.1007/s10986-024-09654-yhttps://hdl.handle.net/11468/29793In this paper, we obtain sharp bounds for the second Hankel determinant of logarithmic coefficients H2,1(Ff/2) of bounded turning functions of order alpha. Furthermore, we obtain sharp bounds of the second Hankel determinant of logarithmic inverse coefficients of H-2,H-1(Ff-1/2), where f(-1) is the inverse function of f. For the class P '(alpha), we conclude that the bounds for H2,1(F-f /2) and H-2,H-1(Ff-1/2) are the same only for 1/4 <= alpha < 1.eninfo:eu-repo/semantics/closedAccessLogarithmic coefficientsInverse coefficientsHankel determinantBounded turning functionsArticle644530545WOS:0013671896000012-s2.0-8521057231610.1007/s10986-024-09654-yQ3Q3
