具有记忆的退化种群方程的渐近能控性

Null controllability for a degenerate population equation with memory

B. Allal, G. Fragnelli, J. Salhi

摘要:

本文研究了一类依赖于时间、空间和年龄的人口模型的零能控性。此外,扩散系数在空间域边界处退化。本文的新颖之处在于,我们第一次考虑了记忆项的存在,这使得计算更加困难。然而,在一个适当的条件下的内核,我们推导出一个零可控性的结果,原问题通过新的Carleman估计的伴随问题相关联的一个合适的非齐次抛物型方程。

英文摘要:

In this paper we consider the null controllability for a population model depending on time, on space and on age. Moreover, the diffusion coefficient degenerate at the boundary of the space domain. The novelty of this paper is that for the first time we consider the presence of a memory term, which makes the computations more difficult. However, under a suitable condition on the kernel we deduce a null controllability result for the original problem via new Carleman estimates for the adjoint problem associated to a suitable nonhomogeneous parabolic equation.
