inequality involving gradient of two harmonic functions
Without reading the paper in detail: If $u \geq v$ and they are equal at a boundary point, then you may have $|\nabla u| \geq |\nabla v|$ or $|\nabla u| \leq |\nabla v|$ with both $u$ and $v$ linear affine. Take $\Omega$ a circle. In the paper one of the functions is related to the capacity of set being investigated. Maybe that is relevant. |

Reconstructing set of points from one-dimensional images
Some more questions: Is J known a priori? Can you select the matrices $M_j$ or are they arbitrary? |

Reconstructing set of points from one-dimensional images
You write that the data includes no knowledge of ordering. What do you mean by this? Does it mean that we do not know if some y in the data is given as $y =M_1 x_4$ or $y=M_2 x_1$, for example? |
