I'm a mathematician currently working in informatics, and at the same time a grad student researching graph theory.

Do graphs with large number of cycles always contain large necklace minor?
What if your graph is disconnected, say it has $ 2^n $ components, each a triangle? |

Analogues of P vs. NP in the history of mathematics
This is a great example, especially because Bolyai has actually expected hyperbolic geometry to be consistent, and mapped out some theorems for it, though he couldn't prove that. |

Is $\lfloor \log(n!)\rfloor \alpha$ equidistributed on the unit circle?
Could you replace the vertical bars with $ \lfloor\dots\rfloor $ floor signs to make the notation more recognizable? |

Simple example of why Differential Equations can be NP Hard
Give a specific decision problem, not just something as vague as "solving differential equations", and ask on cstheory.stackexchange.com please. |

Can we decompose a polynomial into difference of convex polynomials?
mentioned the matrix being symmetric, which I used implicitly. |

Perfectly centered break of a perfectly aligned pool ball rack
How stable is all this to small random errors of the initial position of the balls in the triangle? |

Blocking light with mirrored convex objects
Is there a variant of this in the two-dimensional space? |

Separating unit disks by lines
Your diagrams remind me to the old question mathoverflow.net/questions/20558 What is the minimum N for which there exist N points in the plane that cannot be covered by any number of non-overlapping closed unit discs? |

Thank you. This article definitely gives the definition I asked for. |

Packing and isoperimetrics
Is that related to the paper bag problem en.wikipedia.org/wiki/Paper_bag_problem ? |

Math paper authors' order
For searchability (not that it currently works well on StackExchange, but it might improve in the future), the joke paper you are linking to is Andrew W. Appel, “Is POPL Mathematics or Science?” (1992). |

What is the latest progress in the research on Odd Perfect numbers?
Why is "N is not divisible by 105" so important? |
