How did “normal” come to mean “perpendicular”?
@Emil Jeřábek o̯ is the laryngeal, ĝ is "palatal" or something(nobody knows what it was in reality). The later notation is common (e.g. as in Mallory & Adams, Fortson etc), so what are you referring to as "common notation"? |

@jnovacho yes, the both are from PIE root o̯reĝ- (o̯reĝtos = right, correct, o̯reĝti = guides, directs, o̯reĝs = king, o̯reĝi̯om = kingdom etc) |

Can I suggest this to be moved to Linguistics.SE? |

If two functions are equal to their Newton series, is their composition also equal to its Newton series?
Oh sorry, I see |

So it is good to know that this somehow touches your prevuous research. |

I doubt that is accurate for someone who has theorems in textbooks named after him. |

Sorry I would not ask this, should I know that you're a renowned mathematician. Still your proof is explained in too difficult language at least for me to comprehend. |

I have accepted this answer, although I would prefer it be posted in the linked question. Can you please tell, did you derive this theorem yourself or had you seen it before? |

@fedja What's up with the proof? Can we resonably hope to see it? |

@fedja if you have a link to this property as you stated, this would be a great answer to this question, at least the first part: mathoverflow.net/questions/71206/discrete-analytic-functions |

@fedja how do u know that the Newton series for such function converges? |

@fedja $\sin (\frac{\pi x}{2})$ is entire function? Yes. I suppose its order is less than 1. It does not have convergent Newton series. See here: mathoverflow.net/questions/99166/… |

@fedja by the way, another question is, will a non-zero function which vanishes at any square of integer have its Newton series converging? |

@fedja interesting, but at what conditions it holds then? |
