Abstract | Kac-Moody groups are infinite-dimensional Lie groups over arbitrary
fields or even commutative rings. Tits defined them by writing down
a presentation inspired by the work of Chevalley and Steinberg. This
presentation is "very" infinite, even over a finite field. We found
a simple presentation that improves on existing presentations even
in the classical case.
In particular, one can write down exotic groups like "E10(Z)" easily.
(This particular group is of interest in physics.) |
