    A two cones support theorem
    (2016) Estrada, Ricardo
    We show that if the Radon transform of a distribution $f$ vanishes outside of an acute cone $C_{0}$, the support of the distribution is contained in the union of $C_{0}$ and another acute cone $C_{1}$, the cones are in a suitable position, and $f$ vanishes distributionally in the direction of the axis of $C_{1}$, then actually supp $\operatorname*{supp}f\subset C_{0}$. We show by examples that this result is sharp.
