On a Diffeological Group Realization of Certain Generalized Symmetrizable Kac-Moody Lie Algebras
Journal of Lie Theory, Volume 13 (2003) no. 2, pp. 427-442
We utilize the notion of infinite dimensional diffeological Lie groups and diffeological Lie algebras to construct a Lie group structure on the space of smooth paths into a completion of a generalized Kac-Moody Lie algebra associated to a symmetrized generalized Cartan matrix. We then identify a large normal subgroup of this group of paths such that the quotient group has the sought-after properties of a candidate for a Lie group corresponding to the completion of the initial Kac Moody Lie algebra.
