    • Deformations of modules of maximal grade and the Hilbert scheme at determinantal schemes 

      Kleppe, Jan Oddvar (Journal of Algebra;407, Journal article; Peer reviewed, 2014-04-04)
      Let R be a polynomial ring and M a finitely generated graded R-module of maximal grade (which means that the ideal I_t(\cA) generated by the maximal minors of a homogeneous presentation matrix, \cA, of M has maximal ...

    • Families of Artinian and one-dimensional algebras 

      Kleppe, Jan Oddvar (Journal of Algebra;311, Journal article; Peer reviewed, 2007)
      The purpose of this paper is to study families of Artinian or one dimensional quotients of a polynomial ring R with a special look to level algebras. Let GradAlg^H(R) be the scheme parametrizing graded quotients of R with ...

    • Unobstructedness and dimension of families of Gorenstein algebras 

      Kleppe, Jan Oddvar (Collectanea Mathematica; 58(2), Journal article; Peer reviewed, 2007)
      The goal of this paper is to develop tools to study maximal families of Gorenstein quotients A of a polynomial ring R. We prove a very general Theorem on deformations of the homogeneous coordinate ring of a scheme Proj A ...
