The Light ray transform for pseudo-Euclidean metrics

Divyansh Agrawal, Plamen Stefanov

We study the ray transform $L$ over null (light) rays in the pseudo-Euclidean space with signature $(n^{\prime },n^{\prime \prime })$, $n^{\prime }\ge 2$, $n^{\prime \prime }\ge 2$. We analyze the normal operator $L^{\prime }L$, derive an…
