。在本文中,我们处理与 R ^{2} 中纳维-斯托克斯流的涡度方程相关的扰动热方程。我们得到这个方程的基本解的估计。我们注意到,像我们这样的估计在 Giga、Miyakawa 和 Osada [4] 的论文中发挥了重要作用,他们讨论了 R ^{2} 中纳维斯托克斯方程解的存在性,以初始涡度为测量值。
. In this paper we treat a perturbed heat equation related to the vorticity equation for the Navier-Stokes flow in R ^{2} . We get estimate for the fundamental solution of this equation. We note that estimate like ours played the essential role in the paper by Giga, Miyakawa and Osada [4] where they discussed existence of solution for Navier Stokes equation in R ^{2} with measure as initial vorticity.
