用有限次边界测量识别线性Boltzmann方程中的系数

Identification of the coefficients in the linear Boltzmann equation by a finite number of boundary measurements

Rolci Cipolatti

摘要:

本文考虑了一个含时不定常线性Boltzmann方程的反问题。它涉及通过有限数量的测量边界上的系数的识别。我们证明了总消光系数和碰撞核可以唯一地由边界上的至多k个测量确定,只要这些系数属于有限的k维向量空间。

英文摘要:

In this paper we consider an inverse problem for the time dependent linear Boltzmann equation. It concerns the identification of the coefficients via a finite number of measurements on the boundary. We prove that the total extinction coefficient and the collision kernel can be uniquely determined by at most k measurements on the boundary, provided that these coefficients belong to a finite k-dimensional vector space.
