A number array related to colored necklaces and the primes
A059966 features a reference to a paper by me, and in fact I am well-aware of this relation. :-) |

Is there an English translation of Minding's 1839 paper?
Assuming it's no coincidence that you have a Dutch name, you certainly can read German without needing to look in a dictionary too much; just try;-) The harder part will be to convert the text to modern terminology, but this equally applies to other languages. |

For a Sum-of-Squares cost functions J(x) is it true that J(x)-j* is also SOS?
oh, I just meant to say that in nonlinear least squares the structure of the problem is similar to yours. (And nonlinear least squares have received a lot of attention...) |

Nonlinear least squares problems have this kind of structure. en.wikipedia.org/wiki/Non-linear_least_squares |

nothing to do with group theory IMHO |

it works for a different dehomogenesation, cf. my edited answer. |

oops, sorry, my bad. Now I recall seeing this $f^*_{SOS}=-\infty$ somewhere. Probably some other famous example is not as crazy... |

maximizing a function involving factorial
I'd use the gamma function, which is nice and smooth, and you can use calculus on it. en.wikipedia.org/wiki/Gamma_function |

Why is the spectrum of this matrix product invariant with respect to order of the multiplicants?
shouldn't $n$'s in the formula for $\sigma$ actually be $k$'s? |
