Query: Lieb-Thirring estimates for singular measures   Lieb-Thirring type estimates are proved for the sum of powers of negative
eigenvalues of a Schr\"odinger type operator $(-\Delta)^l -V\mu$ where $\mu$ is
a singular measure in $\mathbb{R}^d,$ satisfying a condition on the measure of
balls and $V$ is a $\mu$-measurable function.
