摘要:

In this article, we prove that viscosity solutions of the parabolic inhomogeneous equations
(n+p)/putpNu=f(x,t)
can be characterized using asymptotic mean value properties for all p≥1, including p = 1 and p = ∞. We also obtain a comparison principle for the non-negative or non-positive inhomogeneous term f for the corresponding initial-boundary value problem and this in turn implies the uniqueness of solutions to such a proble
