Summary
In this paper, we introduce the notion of a "good"  solution of a fully nonlinear parabolic equation and show that "good" solutions are equivalent to Lp -viscosity solutions of such equations. The results here generalize the ones in [8] about "good" solutions of fully nonlinear elliptic equations. We give here an explicit construction of parabolic equations with Lp –strong solutions that approximate some nonlinear parabolic equation and its Lp -viscosity solution.
