The characterization command replaces formulae
in which parts were omitted
by formulae in which those
parts are revealed.
The expressions revealed are the characteristic tuples
of the schema texts
(actually in forms calculated before any proof steps were applied).
{ t } | ![]() | { t ![]() |
( ![]() | ![]() | ![]() ![]() |
( let t ) | ![]() | let t ![]() |
"characterization" e1 e2
This example applies the characterization command to expressions e1 and e2.
