Keywords:
infinite-dimensional complex projective space; infinite-dimensional complex manifold; complete intersection; complex Banach space; complex Banach manifold
Summary:
Let $V$ be an infinite-dimensional complex Banach space and $X \subset {\mathbf {P}}(V)$ a closed analytic subset with finite codimension. We give a condition on $X$ which implies that $X$ is a complete intersection. We conjecture that the result should be true for more general topological vector spaces.
