Description: Equivalent expressions for a restriction of the function operation map. Unlike which is a proper class, can be a set by ofmresex 5764, allowing it to be used as a function or structure argument. By ofmresval 5723, the restricted operation map values are the same as the original values, allowing theorems for to be reused. (Contributed by NM, 20-Oct-2014.) |
