A Unified Range Characterization for the Spherical mean transform

Pradipta Chatterjee, Nisha Singhal, Abhilash Tushir

In this article, we investigate the range characterization for the spherical mean transform (SMT) of functions supported in the unit ball. In earlier works, in the case of odd dime…

d-plane transform: unique and non-unique continuation

Divyansh Agrawal, Nisha Singhal

The -plane transform maps functions to their integrals over -planes in . We study the following question: if a function vanishes in a bounded open set, and its…

On the null space of the backprojection operator and Rubin's conjecture for the spherical mean transform

Divyansh Agrawal, Gaik Ambartsoumian, Venkateswaran P. Krishnan +1

The spherical mean transform associates to a function its integral averages over all spheres. We consider the spherical mean transform for functions supported in the unit ball…

A simple range characterization for spherical mean transform in odd dimensions and its applications

Divyansh Agrawal, Gaik Ambartsoumian, Venkateswaran P. Krishnan +1

This article provides a novel and simple range description for the spherical mean transform of functions supported in the unit ball of an odd dimensional Euclidean space. The new d…
