In this paper we study the modification of the properties of the nucleon in
the nucleus within the quark-soliton model. This is a covariant, dynamical
model, which provides a nonlinear representation of the spontaneously brok
en SU(2)(L)xSU(2)(R) symmetry of QCD. The effects of the nuclear medium are
accounted for by using the Wigner-Seitz approximation and therefore reduci
ng the complex many-body problem to a simpler single-particle problem. We f
ind a minimum in the binding energy at finite density, a change in the isos
calar nucleon radius, and a reduction of the in-medium pion decay constant.
The latter is consistent with a partial restoration of chiral symmetry at
finite density, which is predicted by other models.
