Rank ring
In mathematics, a rank ring is a ring with a real-valued rank function behaving like the rank of an endomorphism. introduced rank rings in his work on continuous geometry, and showed that the ring associated to a continuous geometry is a rank ring.
==Definition==

defined a ring to be a rank ring if it is regular and has a real-valued rank function ''R'' with the following properties:
*0 ≤ ''R''(''a'') ≤ 1 for all ''a''
*''R''(''a'') = 0 if and only if ''a'' = 0
*''R''(1) = 1
*''R''(''ab'') ≤ ''R''(''a''), ''R''(''ab'') ≤ ''R''(''b'')
*If ''e''2 = ''e'', ''f''2 = ''f'', ''ef'' = ''fe'' = 0 then ''R''(''e'' + ''f'') = ''R''(''e'') + ''R''(''f'').
