The goal of this paper is to extend and complete the results given by the authors in an earlier paper and determine under weakened numerical assumptions the dimension of $ W(\underline{b};\underline{a})$ as well as whether the closure of $ W(\underline{b};\underline{a})$ is a generically smooth irreducible component of $ \textrm{Hilb}^p(\mathbb{P}^{n})$.13 p.application/pdfeng(c) American Mathematical Society (AMS), 2011ÀlgebraEsquemes (Geometria algebraica)AlgebraSchemes (Algebraic geometry)info:eu-repo/semantics/article5891622016-03-17info:eu-repo/semantics/openAccess
