Abstract:
We study the local solvability of the tangential
Cauchy-Riemann equation on an open
neighborhood
of a point
when
is a generic -concave
manifold of real codimension
in
,
where
.
Our method is to first derive a homotopy
formula for
in
when
is the
intersection of
with a strongly pseudoconvex domain. The
homotopy formula gives a local solution operator
for any
-closed form on
without shrinking.
We obtain Hölder and
estimates up to the boundary
for the solution operator.

Nous
construisons une formule d'homotopie pour le

lorsque

Nous en déduisons des estimations
