Abstract:
We use the mode-coupling approximation to derive a closed system of equations
for the Green's functions for the transverse and longitudinal spin components
taking the sum rules related to the finiteness of the spin into account
exactly.
Keywords:
mode-coupling approximation, sum rules for spin operators.
