Abstract
We consider the family of all analytic and univalent functions in the unit disk D:= {z ? ?: |z| < 1} of the form f (z) = z + a2z2 + a3z3 + � � � . We obtain the sharp bounds of the second-Hankel determinant of logarithmic coefficients for some subclasses of analytic functions. � Rocky Mountain Mathematics Consortium.
