Definition df-res 4701
 Description: Define the restriction of a class. Definition 6.6(1) of [TakeutiZaring] p. 24. For example, the expression (used in reeff1 12400) means "the exponential function e to the x, but the exponent x must be in the reals" (df-ef 12349 defines the exponential function, which normally allows the exponent to be a complex number). Another example is that (ex-res 20828). (Contributed by NM, 2-Aug-1994.)
