| Description: Every real number having
a reciprocal or equaling zero is equivalent to
real number trichotomy.
This is the key part of the definition of what is known as a discrete field, so "the real numbers are a discrete field" can be taken as an equivalent way to state real trichotomy (see further discussion at trilpo 15986). (Contributed by Jim Kingdon, 10-Jun-2024.) |
