                   ÃÊ·Ï:  I will talk about new deformation of the convolution algebra $L^1(G)$ and the Fourier algebra $A(G)$. The deformed algebras are completely isomorphic to an operator algebra under some condition and we can read group information such as the dimension of connected compact Lie group or the growth order of discrete group by this characterization.

ÃÊ·Ï: We give a systematic study of  Sobolev, Besov and Triebel-Lizorkin spaces  on a noncommutative torus. These spaces share many properties with their classical counterparts. We prove the lifting theorem for all these spaces and a Poincare type inequality for Sobolev spaces. We also show that the Sobolev space coincides with the Lipschitz space studied by Weaver. We establish the embedding inequalities of all these spaces, including the Besov and Sobolev embedding theorems. We obtain Littlewood-Paley type characterizations for Besov and Triebel-Lizorkin spaces in a general way, as well as the concrete ones in terms of the Poisson, heat semigroups and  differences. As a consequence of the characterization of the Besov spaces by differences, we extend to the quantum setting the recent results of  Bourgain-Brezis -Mironescu and Maz'ya-Shaposhnikova on the limits of Besov norms. We investigate the interpolation of all these spaces. Finally, we show that the completely bounded Fourier multipliers on all these spaces coincide with those on the corresponding spaces on the usual torus.

In this talk we will explain Pisier's similarity degree for completely contractive Banach algebras and apply to the case of Fourier algebra A(G). We will show that for infinite QSIN groups (containing amenable or discrete groups) the similarity degree of the corresponding Fourier algebra is exactly 2. As a consequence we prove the following Fourier algebra version of Dixmier's similarity problem: any cb-homomorphism from A(G) to B(H) is similar to *-representation.

The previous results in this direction were based upon the local representation of the representative of the element in the quotient algebra, and the low dimension of the space X. We suggest a way to overcome these conditions with some machinaries in operator K-theory.

Àå¼Ò: 129µ¿ 301È£ 
ÃÊ·Ï: 
Fourier algebras of locally compact groups are important class of commutative Banach algebras containing much information on the underlying groups enough to distinguish them. However, extracting specific information on the group from the Fourier algebra is a highly nontrivial procedure in general. In this talk we will focus on the compact Lie group case and will discuss about how we can get the dimension information from the Banach algebraic property of the associated Fourier algebra. The key ingredient is making the Fourier algebra weighted. We will begin with the definition of Fourier algebras on compact groups and their weighted versions. 

The talk is based on a joint work with M. Ghandehari/E. Samei/N. Spronk.

Fourier algebras of locally compact groups are important class of commutative Banach algebras containing much information on the underlying groups enough to distinguish them. However, extracting specific information on the group from the Fourier algebra is a highly nontrivial procedure in general. In this talk we will focus on the compact Lie group case and will discuss about how we can get the dimension information from the Banach algebraic property of the associated Fourier algebra. The key ingredient is making the Fourier algebra weighted. We will begin with the definition of Fourier algebras on compact groups and their weighted versions. 

The talk is based on a joint work with M. Ghandehari/E. Samei/N. Spronk.
