algebra

The following files are ported from the standard library. If anything needs to be changed, it is probably a good idea to change it in the standard library and then port the file again (see also script/port.pl).

• binary : properties of binary operations
• relation : properties of relations
• group
• ring
• order
• ordered_group
• ordered_ring
• field

Files which are not ported:

• hott : Basic theorems about the algebraic hierarchy specific to HoTT
• trunc_group : truncate an infinity-group to a group
• homotopy_group : homotopy groups of a pointed type
• e_closure : the type of words formed by a relation

Subfolders:

• category : Category Theory
