Poisson kernel is the only approximative identity asymptotically multiplicative on
$H^\infty$
H. Wolf
,
V. P. Havin
Abstract:
Every approximative identity asymptotically multiplicative with respect to
$H^\infty(\mathbb{R})$
(or to
$H^\infty(\mathbb{T})$
) is necessarily a shift and a contraction of the Poisson kernel.
