LOCAL SOBOLEV ESTIMATES OF A FUNCTION BY MEANS OF ITS RADON TRANSFORM
2010 (English)In: Inverse Problems and Imaging, ISSN 1930-8337, Vol. 4, no 4, 721-734 p.Article in journal (Refereed) Published
In this article, we will define local and microlocal Sobolev seminorms and prove local and microlocal inverse continuity estimates for the Radon hyperplane transform in these seminorms. The relation between the Sobolev wavefront set of a function f and of its Radon transform is well-known . However, Sobolev wavefront is qualitative and therefore the relation in  is qualitative. Our results will make the relation between singularities of a function and those of its Radon transform quantitative. This could be important for practical applications, such as tomography, in which the data are smooth but can have large derivatives.
