| ``Notation for upper bound''
by porton on 2008-02-29 11:45:24 |
|
| Is there any conventional math symbol which means "a is an upper bound of X"?
Or maybe there is some symbol which means "the set of all upper bounds of X"?
What I want is to write phrase "a is an upper bound of X" symbolically (not by English words).
And dually for lower bounds.
