Colossally Abundant Number - Relation To The Riemann Hypothesis

Relation To The Riemann Hypothesis

In the 1980s Guy Robin showed that the Riemann hypothesis is equivalent to the assertion that the following inequality is true for all n > 5040:

This inequality is known to fail at n = 5040, but Robin showed that if the Riemann hypothesis is true then this is the last integer for which it fails. The inequality is now known as Robin's inequality after his work. It is known that Robin's inequality, if it ever fails to hold, will fail for a colossally abundant number n, thus the Riemann hypothesis is in fact equivalent to Robin's inequality holding for every colossally abundant number n > 5040.

Famous quotes containing the words relation to, relation and/or hypothesis:

    A theory of the middle class: that it is not to be determined by its financial situation but rather by its relation to government. That is, one could shade down from an actual ruling or governing class to a class hopelessly out of relation to government, thinking of gov’t as beyond its control, of itself as wholly controlled by gov’t. Somewhere in between and in gradations is the group that has the sense that gov’t exists for it, and shapes its consciousness accordingly.
    Lionel Trilling (1905–1975)

    The difference between objective and subjective extension is one of relation to a context solely.
    William James (1842–1910)

    It is an hypothesis that the sun will rise tomorrow: and this means that we do not know whether it will rise.
    Ludwig Wittgenstein (1889–1951)
