Coassociativity of∆ follows from associativity of the product in G. To see that the cancellation
property holds, note that (A⊗ 1)∆(A) is the unital∗-subalgebra of C (G× G) spanned by all …

Associated to a finite graph X is its quantum automorphism group G. The main problem is to
compute the Poincaré series of G, meaning the series f (z)= 1+ c1z+ c2z2+⋯ whose …

If B is \bfC^*-algebra of dimension 4≦n<∞ then the finite dimensional irreducible
representations of the compact quantum automorphism group of B, say G_aut(B), have the …

Easy quantum groups form a class of compact matrix quantum groups which are completely
determined by set partitions. They have been defined in 2009 by Banica and Speicher in the …

We define concepts of amenability and co-amenability for locally compact quantum groups
in the sense of J. Kustermans and S. Vaes. Co-amenability of a lcqg (locally compact …

We study the concept of co-amenability for a compact quantum group. Several conditions
are derived that are shown to be equivalent to it. Some consequences of co-amenability that …

We consider the hypercube in $\mathbb R^ n $, and show that its quantum symmetry group
is a $ q $-deformation of $ O_n $ at $ q=-1$. Then we consider the graph formed by $ n …

The reaction cross section for B 8 and Be 7 and the breakup cross section for B 8 on silicon
have been measured for incident energies between 10 and 40 MeV/nucleon with a stack of …

We develop a representation theory for λ λ-lattices, arising as standard invariants of
subfactors, and for rigid C*-tensor categories, including a definition of their universal C …
