Abstract. We treat the boundary problem for complex varieties
with isolated singularities, which are contained in a certain class
of strongly pseudoconvex, not necessarily bounded open subsets of
Cn

1. Introduction
Let M be a smooth and oriented real (2m + 1)submanifold of some
ncomplex manifold X. A natural question arises, whether M is the
boundary of an (m + 1)complex analytic subvariety of X. This prob
lem, the so called boundary problem, has been widely treated over the
past fifty years when M is compact and X is Cn
or CPn
.
The case when M is a compact, connected curve in X = Cn
(m = 0),
has been first solved by Wermer [12] in 1958. Later on, in 1975, Harvey
