Sets of spreads in graphs
@Anurag I don't have an example - I am hoping to construct one for an argument I am working on. Haemers and Tonchev say in the paper that they found five different spreads but don't say whether those spreads were pairwise disjoint. If you are interested (I thought you might be :) I'll be happy to disucss this further. |

@domotorp I think that I need Baranyai's conclusion but for other hypergraphs than the complete ones. |

Open problems in compressed sensing
@YemonChoi Well, I have an idea of what compressed sensing is - having read some articles and knowing a thing or two about linear algebra and signal processing, as background. But I cannot really tell which are the more fundamental problems, as opposed to sheer technicalities. That's why I asked for knowledgeable people, to give their estimate of what the main problems are - a bit like my old question mathoverflow.net/questions/118545/… which I think worked rather well. I did not ask anyone to write an encyclopaedia entry for me. |

Navigation in a graph
Can it happen that there is one short path from $x$ to $y$ but it passes "far from" $T$? In that case I don't see how you can do anything. |

How many isolated roots can a polynomial in $z$ and $\overline{z}$ have?
@ChristianRemling I am not so sure - that question has two general unrelated variables. I am only interested in the case when $y=\overline{x}$. |

Thanks to all who answered. Now I would like to sharpen the question - what about singular zeros? |
