WebG. As in the Kac algebra case, we use order properties of A∗∗ to determine L1(G) inside A∗. Our characterisation of such isometric isomorphisms involves the intrinsic group of A∗∗, but we show that this is always canonically isomorphic to the intrinsic group of L∞(G).

Webstanding the structure of Kac–Moody algebras is an essential step towards a better understanding of the corresponding Kac–Moody groups; these groups, introduced in the late 1980’s, turn out to exhibit a very rich structure, paralleling that of semisim-ple algebraic groups, and have become over the last decades prominent objects of Web17 de jun. de 2007 · We provide an intrinsic definition of the fundamental group of a linear category over a ring as the automorphism group of the fibre functor on Galois coverings. … WebThe discussion is carried out with the use of the theory of Kac algebras and its generalizations.
