A generalization of Chebyshev polynomials
Added tag "approximation-theory" which is the area for this problem. (For all I know this problem is solved in the standard textbooks in that area.) |

Is every polynomial a factor of a trinomial?
How many real zeros can a trinomial have? |

Existence of functions on finite sets with specific propertise
I suppose propertise is sort of like expertise. I like it! Perhaps the "propertise" of an object is not just a miscellaneous list of properties, but the gestalt of all relevant properties taken together. |

Natural topologies for the space of rational functions
It seems in this topology, you cannot change the degree when you converge. Constants can converge to constants. Degree one maps (like $z/(z-1/n)$) cannot converge to a constant (like $1$). |

Eliminating Gibbs phenomenon, and approximating with jumping functions in Fourier Analysis : An attempt and a question in this regard
Aside: the man's name was Gibbs, not Gibb. So use any of these: "The Gibbs phenomenon" ... "Gibbs' phenomenon" ... "Gibbs' phenomenon". |

Proof that derivative of Hurwitz Zeta by the first argument is not expressable in terms of Hurwitz Zeta
Definition... $$\zeta(s,q) := \sum_{n=0}^\infty\frac{1}{(q+n)^s}$$ with analytic continuation. en.wikipedia.org/wiki/Hurwitz_zeta_function |
