具有记忆的四阶Cattaneo热传导方程
On the fourth order Cattaneo equation of heat conduction with memory
摘要:
当某个小参数为零时,利用更一般的四阶偏微分方程得到了Cattaneo提出的有限传播速度热传导方程。在文献中似乎基本上忽略了这个四阶方程,特别是当它受到非齐次边界条件的约束时。在本文中,我们研究它的适定性和渐近行为时,某些系数趋于奇异值。
英文摘要:
The well known heat equation with finite speed of propagation proposed by Cattaneo is obtained by a more general fourth order PDE when a certain (small) parameters is put equal to zero. It seems that this fourth order equation has been essentially overlooked in the literature, in particular when it is subject to non homogeneous boundary conditions. In this paper we examine its well posedness and the asymptotic behavior when certain coefficients tend to singular values.
