An explicit minorant for the amenability constant of the Fourier algebra
Y. Choi
We show that if a locally compact group is non-abelian then the amenability constant of its Fourier algebra is , extending a result of Johnson (JLMS, 1994) who proved…
A short proof that is not amenable
Yemon Choi
Non-amenability of has been surprisingly difficult to prove for the classical Banach spaces, but is now known for and for all …
Dual convolution for the affine group of the real line
Yemon Choi, Mahya Ghandehari
The Fourier algebra of the affine group of the real line has a natural identification, as a Banach space, with the space of trace-class operators on $L^2({\mathbb R}^\times, dt/ |t…
Constructing alternating 2-cocycles on Fourier algebras
Yemon Choi
Building on recent progress in constructing derivations on Fourier algebras, we provide the first examples of locally compact groups whose Fourier algebras support non-zero, altern…
