HOL Light is a computer program to help users prove interesting mathematical
|
||
|
|
theorems completely formally in Higher-Order Logic. It sets a very exacting
|
||
|
|
standard of correctness, but provides a number of automated tools and
|
||
|
|
pre-proved mathematical theorems (e.g., about arithmetic, basic set theory and
|
||
|
|
real analysis) to save the user work. It is also fully programmable, so users
|
||
|
|
can extend it with new theorems and inference rules without compromising its
|
||
|
|
soundness.
