ATS Theorem - Remark

Remark

If the parameters and are integers, then it is possible to substitute the last relation by the following ones:

\sum_{a<k\le b} e^{2\pi i f(k)} = \int_a^be^{2\pi i f(x)}dx + \frac12e^{2\pi i f(b)} - \frac12e^{2\pi i f(a)} + \theta\frac{2\delta}{1-\delta},

Famous quotes containing the word remark:

    “Your remark that clams will lie quiet if music be played to them, was superfluous—entirely superfluous.”
    —Mark Twain [Samuel Langhorne Clemens] (1835–1910)

    “The Cretans are always liars, evil beasts, slow bellies.”
    —Bible: New Testament St. Paul, in Titus, 1:12.

    Cited by Paul, this remark is attributed to Epimenides.

    “I know not whether the remark is to our honour or otherwise, that lessons of wisdom have never such power over us, as when they are wrought into the heart, through the ground-work of a story which engages the passions: Is it that we are like iron, and must first be heated before we can be wrought upon?”
    —Laurence Sterne (1713–1768)
