Abstract

In this paper, we introduce the \(L_q\)-reflector measure as a class of geometric optics measures which is a natural \(L_q\) extension of the reflector measure. The \(L_q\)-reflector measure gives rise to one related Minkowski-type problem, namely the \(L_q\)-reflector inverse problem. It asks for necessary and sufficient conditions on a given measure \(\mu \) in order for it to be the \(L_q\)-reflector measure of a reflector. The main concentration properties of reflectors and measures allow us to establish direct variational proofs. As a result, we solve the existence part of the \(L_q\)-reflector inverse problem for all real numbers q.
