On the $X$-ray transform of planar symmetric 2-tensors
摘要:
本文研究了欧氏平面上支持在严格凸有界子集上的2-张量的衰减$X$射线变换。我们表征其范围和重建所有可能的2张量产生相同的$X$射线数据。的特征是在一个希尔伯特变换与$A$ -解析地图的意义上的Bukhgeim。
英文摘要:
In this paper we study the attenuated $X$-ray transform of 2-tensors supported in strictly convex bounded subsets in the Euclidean plane. We characterize its range and reconstruct all possible 2-tensors yielding identical $X$-ray data. The characterization is in terms of a Hilbert-transform associated with $A$-analytic maps in the sense of Bukhgeim.
