The Biduality Problem and M-Ideals in Weighted Spaces of Holomorphic Functions

Christopher Boyd, Pilar Rueda

Given a weight

v v
on an open subset
U U
of
{\bf C}^n C n
,
{\cal H}_v(U) H v ( U )
(resp.
{\cal H}_{v_o}(U) H v o ( U )
) denotes the Banach space of holomorphic functions
f f
on
U U
such that
vf v f
is bounded on
U U
(resp. converges to
0 0
on the boundary of
U U
). We show that
{\cal H}_v(U) H v ( U )
is canonically isometrically isomorphic to the bidual of
{\cal H}_{v_o}(U) H v o ( U )
if and only if
{\cal H}_{v_o}(U) H v o ( U )
is an M-ideal in
{\cal H}_v(U) H v ( U )
and the associated weights
\tilde v_o v ~ o
and
\tilde v v ~
coincide
