We consider a class of nonautonomous elliptic operators A with unbounded coefficients defined in $[0,T]\times\R^N$ and we prove optimal Schauder estimates for the solution to the parabolic Cauchy problem $D_tu=$A$u+g$, $u(0,\cdot)=f$.
Keywords: discontinuous coefficients, optimal Schauder estimates., nonautonomous elliptic and parabolic operators with unbounded coefficients.
