WebThe restriction of the coordinate ring to the Kac-Moody group is the algebra of strongly regular functions introduced by V. Kac and D. Peterson. This monoid has similar structural properties as a reductive algebraic monoid. In particular it is unit regular, its idempotents related to the faces of the Tits cone. Web10 de set. de 2002 · It is shown that, for a minimal action α of a compact Kac algebra K on a factor A, the group of all automorphisms leaving the fixed-point algebra A α pointwise invariant is topologically isomorphic to the intrinsic group of the dual Kac algebra K ̂.As an application, in the case where dim K <,∞, the left (in fact, two-sided) coideal of K …
Web2-algebra (or a Hopf version) should be compared with the difficulty in defining precisely the meaning of quantum groups (or quantum algebras). The analogy is actually expected to be meaningful: while quantization turns certain algebras into quantum algebras, “categorifica-tion” should turn those algebras into 2-algebras.
