Short Description
Meyer's theorem states that an indefinite integral quadratic form Q in n variables, n ≥ 5, nontrivially represents zero, i.e. there exists an non-zero vector x with integer components such that Q(x) = 0. The Oppenheim conjecture can be viewed as an analogue of this statement for forms Q that are not multiples of a rational form. It states that in this case, the set of values of Q on integer vectors is a dense subset of the real line.

Famous quotes containing the words short and/or description:
“Swift as a shadow, short as any dream,
Brief as the lightning in the collied night,
That in a spleen unfolds both heaven and earth,
And, ere a man hath power to say “Behold!”
The jaws of darkness do devour it up.
So quick bright things come to confusion.”
—William Shakespeare (1564–1616)
“As they are not seen on their way down the streams, it is thought by fishermen that they never return, but waste away and die, clinging to rocks and stumps of trees for an indefinite period; a tragic feature in the scenery of the river bottoms worthy to be remembered with Shakespeare’s description of the sea-floor.”
—Henry David Thoreau (1817–1862)
