The Decay Rate of Solution to Incompressible Porous Medium Equations
摘要
Abstract
A decay rate of the solution was derived to the incompressible porous medium equations governed by Darcy's law, with the property of the semigroup operator e-t(-Δ)a and L2-norms.A new concise method was established to get the better decay rate in L2 (R3 ), which avoided using the Fourier splitting technique completely and a rough decay estimates of ‖ ▽T(t) ‖ L2.关键词
