  The rheology of dense sheared granular liquids is investigated based on the
mode-coupling theory (MCT). This extended MCT includes correlations for the
density-current mode as well as the density-density correlation mode, and a
self-consistent coupling equation for the energy balance condition. The
extended MCT exhibits disappearance of the two-step relaxation of the
density-density correlation function, and also successfully reproduces the
density dependence of the shear viscosity for volume fractions between 0.50 and
0.60, if we shift the density. However, it predicts unphysical tendency for the
granular temperature. The cause of this drawback and the possibilities of its
amendment are discussed.
