On amenability and co-amenability of algebraic quantum groups and their corepresentations
We introduce and study several amenability properties for unitary
corepresentations and *-representations of algebraic quantum groups, which may
be used to characterize amenability or co-amenability of such groups. As a
background for this study, we also investigate the involved tensor
C*-categories.Comment: 46 pages, (some misprints corrected, a couple of remarks and a new

Amenability and co-amenability of algebraic quantum groups
We define concepts of amenability and co-amenability for algebraic quantum
groups in the sense of A. Van Daele. We show that co-amenability of an
algebraic quantum group always implies amenability of its dual. Various
necessary and/or sufficient conditions for amenability or co-amenability are
obtained. Co-amenability is shown to have interesting consequences for the
modular theory in the case that the algebraic quantum group is of compact type.Comment: 25 pages, with some minor corrections, as to appear in the IJMM
Quantized algebras of functions on homogeneous spaces with Poisson stabilizers
Let G be a simply connected semisimple compact Lie group with standard
Poisson structure, K a closed Poisson-Lie subgroup, 0<q<1. We study a
quantization C(G_q/K_q) of the algebra of continuous functions on G/K. Using
results of Soibelman and Dijkhuizen-Stokman we classify the irreducible
representations of C(G_q/K_q) and obtain a composition series for C(G_q/K_q).
We describe closures of the symplectic leaves of G/K refining the well-known
description in the case of flag manifolds in terms of the Bruhat order. We then
show that the same rules describe the topology on the spectrum of C(G_q/K_q).
Next we show that the family of C*-algebras C(G_q/K_q), 0<q\le1, has a
canonical structure of a continuous field of C*-algebras and provides a strict
deformation quantization of the Poisson algebra \C[G/K]. Finally, extending a
result of Nagy, we show that C(G_q/K_q) is canonically KK-equivalent to C(G/K).Comment: 23 pages; minor changes, typos correcte

En les sĂndromes en les quals els criteris sĂłn els de diagnòstic clĂnic (per exemple, sĂndromes endocrines) no s’especifiquen.
