  An analytical approach is developed to the problem of computation of monotone
Riemannian metrics (e.g. Bogoliubov-Kubo-Mori, Bures, Chernoff, etc.) on the
set of quantum states. The obtained expressions originate from the Morozova,
Chencov and Petz correspondence of monotone metrics to operator monotone
functions. The used mathematical technique provides analytical expansions in
terms of the thermodynamic mean values of iterated (nested) commutators of a
model Hamiltonian T with the operator S involved through the control parameter
$h$. Due to the sum rules for the frequency moments of the dynamic structure
factor new presentations for the monotone Riemannian metrics are obtained.
Particularly, relations between any monotone Riemannian metric and the usual
thermodynamic susceptibility or the variance of the operator $S$ are discussed.
If the symmetry properties of the Hamiltonian are given in terms of generators
of some Lie algebra, the obtained expansions may be evaluated in a closed form.
These issues are tested on a class of model systems studied in condensed matter
physics.
