Á¦¸ñ: Weak amenability of Fourier algebras and local synthesis of the anti-diagonal

ÀϽÃ: 2014³â 11¿ù 28ÀÏ(±Ý) 10:30-12:00

Àå¼Ò: 129µ¿ 301È£

ÃÊ·Ï:

Since the work of Johnson characterizing amenability of a locally compact group G in terms of Banach algebra amenability of the convolution algebra L_1(G), questions of characterizing various amenabilities of group related Banach algebras have been central theme of abstract harmonic analysis. For example, Ruan proved that operator space amenability of the Fourier algebra A(G) is equivalent to the amenability of G and Forrest/Runde showed that amenability of A(G) is equivalent to G being virtually abelian. In this talk we will focus on the weak amenability problem of Fourier algebras on Lie groups. We show that for a Lie group G, its Fourier algebra A(G) is weakly amenable if and only if its connected component of the identity G_e is abelian. Our main new idea is to show that for connected G, weak amenability of A(G) implies that the anti-diagonal of the product group G \times G, is a set of local synthesis for

A(G\times G). We then to show that this cannot happen if G is non-abelian.


This is a joint work with Jean Ludwig (Metz), Ebrahim Samei (Saskatchewan) and Nico Spronk (Waterloo).

ÃÊ·Ï: Free Araki-Woods factors are certain type III generalizations of free group factors. In this talk, we will explain how these von Neumann algebras arise quite naturally from the perspective of compact quantum groups. We will show that any (almost periodic) free Araki-Woods factor can be realized as a Haar distributional limit (with respect to the Haar state) of the generators of a suitably chosen family of Van Daele and Wang's non-unimodular free orthogonal quantum groups. We will also explain how this class of quantum groups naturally appears as distributional symmetries of free Araki-Woods factors. This talk is based on joint work with Kay Kirkpatrick.

ÀϽÃ: 2014³â 9¿ù 12ÀÏ(±Ý) 10:30-12:00

Àå¼Ò: 129µ¿ 301È£

ÃÊ·Ï:

Let $G$ be a compact group and $ZA(G)$ be the "central Fourier algebra", i.e. the algebra of those $u$ in A(G)$ for which $u(x)=(yxy^{-1})$ for each $x,y$ in $G$.  I will discuss amenability and weak amenability for this algebra. The latter property holds exactly when $G$ admits no connected non-abelian subgroups. For virtually abelian $G$, $ZA(G)$ is amenable. I will present evidence for the converse, in particular infinite products of finite groups.


This represents joint work with M. Alaghmandan.

Á¦¸ñ: Amenability properties of central Fourier algebras of compact groups

ÀϽÃ: 2014³â 9¿ù 12ÀÏ(±Ý) 10:30-12:00

Àå¼Ò: 129µ¿ 301È£

ÃÊ·Ï:

Let $G$ be a compact group and $ZA(G)$ be the "central Fourier algebra", i.e. the algebra of those $u$ in A(G)$ for which $u(x)=(yxy^{-1})$ for each $x,y$ in $G$.  I will discuss amenability and weak amenability for this algebra. The latter property holds exactly when $G$ admits no connected non-abelian subgroups. For virtually abelian $G$, $ZA(G)$ is amenable. I will present evidence for the converse, in particular infinite products of finite groups.


This represents joint work with M. Alaghmandan.

ÃÊ·Ï: We consider Hilbert spaces of functions on infinite graphs, and their compactifications. We arrived at a sampling formula in the spirit of Shannon; the idea is that we allow for sampling of functions f defined on a continuum completion of an infinite graph G, sampling the continuum by values of f at points in the graph G.


Rather than the more traditional frequency analysis of band-limited functions from Shannon, our analysis is instead based on reproducing kernel Hilbert spaces built from a prescribed infinite system of resistors on G.

ÀϽÃ: 2014³â 3¿ù 14ÀÏ(±Ý) 10:30-12:00

Àå¼Ò: 129µ¿ 301È£

ÃÊ·Ï: In this talk we will discuss a model for a weighted version of Fourier algebras on non-compact Lie groups. Note that the Fourier algebra is the L1-algebra of a co-commutative (l.c.) quantum group. We first introduce the concept of "weight" in this context and some examples of "weights". By introducing a "weight" we finally get a new commutative Banach algebra. If we recall that the spectrum of the Fourier algebra is nothing but the underlying group itself (as a topological space), then it is natural to be interested in determining the spectrum of weighted algebras. We will demonstrate that the spectrum of the resulting commutative Banach algebra is realized inside the complexification of the underlying Lie group by focusing on the case of Heisenberg group and determine them in some concrete cases.

Á¦¸ñ: Weighted Fourier algebras on non-compact Lie groups and their spectrum

ÀϽÃ: 2014³â 3¿ù 14ÀÏ(±Ý) 10:30-12:00

Àå¼Ò: 129µ¿ 301È£

ÃÊ·Ï: In this talk we will discuss a model for a weighted version of Fourier algebras on non-compact Lie groups. Note that the Fourier algebra is the L1-algebra of a co-commutative (l.c.) quantum group. We first introduce the concept of "weight" in this context and some examples of "weights". By introducing a "weight" we finally get a new commutative Banach algebra. If we recall that the spectrum of the Fourier algebra is nothing but the underlying group itself (as a topological space), then it is natural to be interested in determining the spectrum of weighted algebras. We will demonstrate that the spectrum of the resulting commutative Banach algebra is realized inside the complexification of the underlying Lie group by focusing on the case of Heisenberg group and determine them in some concrete cases.
