We study the light-cone Siegel transform, transforming functions on the light cone of a rational indefinite quadratic form *Q* to a function on the homogenous space *\text{SO}^+_Q(\mathbb{Z})\backslash \text{SO}^+_Q(\mathbb{R})*. In particular, we prove a second moment formula for this transform for forms of signature *(n+1,1)*, and show how it can be... Show more
