一类具有大小结构的种群模型的反问题

On the Inverse Problem for a Size-Structured Population Model

Benoit Perthame, Jorge P. Zubelli

摘要:

我们考虑一个大小结构的细胞分裂模型,并解决这个问题,确定分裂(出生)率从测得的稳定的大小分布的人口。我们将此问题表示为一个位于射线上的积分微分方程的反问题。我们首先开发了一个经常依赖理论的解决方案中的系数,其次,一种新的正则化技术来解决这个反问题,考虑到特定的性质的方程。我们的结果也依赖于广义相对熵估计和相关的Poincaré不等式。

英文摘要:

We consider a size-structured model for cell division and address the question of determining the division (birth) rate from the measured stable size distribution of the population. We formulate such question as an inverse problem for an integro-differential equation posed on the half line. We develop firstly a regular dependency theory for the solution in terms of the coefficients and, secondly, a novel regularization technique for tackling this inverse problem which takes into account the specific nature of the equation. Our results rely also on generalized relative entropy estimates and related Poincaré inequalities.
