WebLet A be any Kac-Moody algebra all of whose real roots have norm 2.(Everything here can be generalized to all Kac-Moody algebras but becomes a lot more complicated, so for simplicity I will mostly just describe this case.) A is deﬁned by certain generators and relations depending on the Cartan matrix of A, and one of the most important ...

WebAlso, in recent times, the topic of "quantum groups" has become very fashionable and attracted the attention of more and more mathematicians and theoret ical physicists. One is still missing a good characterization of quantum groups among Hopf algebras, similar to the character ization of Lie groups among locally compact groups. 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). We ﬁnish to showing

WebIn this paper we use the recent developments in the representation theory of locally compact quantum groups, to assign, to each locally compact quantum group G, a locally compact group ~G which is the quantum version of point-masses, and is an invariant for the latter.
