An elementary approach to the dimension of measures satisfying a first-order linear PDE constraint

A Arroyo-Rabasa - Proceedings of the American Mathematical Society, 2020 - ams.org
We give a simple criterion on the set of probability tangent measures $\operatorname
{Tan}(\mu, x) $ of a positive Radon measure $\mu $, which yields lower bounds on the …
