具有一般测度的线性抛物型方程解的渐近性

Asymptotic behavior of solutions for linear parabolic equations with general measure data

Francesco Petitta

摘要:

本文研究线性抛物型方程解的渐近行为,方程的模型是$t$,其中$μ$是一个一般的,可能奇异的,不依赖于时间的Radon测度,而$u_0\in L^{1}(Ω)$ .我们证明了对偶解的存在性和唯一性,并收敛于对偶解(如G. Stampacchia)的相关椭圆问题。

英文摘要:

In this paper we deal with the asymptotic behavior as $t$ tends to infinity of solutions for linear parabolic equations whose model is $$ \begin{cases} u_{t}-Δu = μ& \text{in}\ (0,T)\timesΩ,\\[0.7 ex] u(0,x)=u_0 & \text{in}\ Ω, \end{cases} $$ where $μ$ is a general, possibly singular, Radon measure which does not depend on time, and $u_0\in L^{1}(Ω)$. We prove that the duality solution, which exists and is unique, converges to the duality solution (as introduced by G. Stampacchia) of the associated elliptic problem.
