# Definition:Dual Ordering/Strict/Notation

## Definition

To denote the dual of an strict ordering, the conventional technique is to reverse the symbol.

Thus:

$\succ$ denotes $\prec^{-1}$

and so:

$a \prec b \iff b \succ a$

Similarly for the standard symbol used to denote a strict ordering on numbers:

$>$ denotes $<^{-1}$

and so on.
