Let (U) denote the algebra of holomorphic functions on an open subset U ⊂ ℂⁿ and Z ⊂ (U) its finite-dimensional vector subspace. By the theory of least spaces of de Boor and Ron, there exists a projection from the local ring onto the space of germs of elements of Z at b. At a general point b ∈ U its kernel is an ideal and induces the structure of an Artinian algebra on . In particular, this holds at points where the kth jets of elements of Z form a vector bundle for each k ∈ ℕ. For an embedded...
