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? |

eigenvalue estimate of the adjacency matrix
@DelioMugnolo Which paper would that be? Thanks. |

Just making sure: are you interested in lower bounds for $\lambda_{\min}$ or for $|\lambda_{\min}|$? |

nonnegativity conditions for a polynomial in two variables
Can you give me a reference for the quartic case? This is a bit related to copositive matrices (a matrix can be thought of as a homogenous 2nd degree polynomial) but right now I can't offer any tangible result. |

@DavidHandelman Can you please elaborate a bit? 10x! |

Irinically, my original overwrought proof used the Gruss inequality - which is a complement to Chebyshev. So it all comes together. :) |
