1. 1. Compactifying locally Cohen-Macaulay projective curves

   Författare :Morten Hønsen; Dan Laksov; Kristian Ranestad; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cohen-Macaulay compactification; curves; algebraic space; Algebra and geometry; Algebra och geometri;

   Sammanfattning : We define a moduli functor parametrizing finite maps from a projective (locally) Cohen-Macaulay curve to a fixed projective space. The definition of the functor includes a number of technical conditions, but the most important is that the map is almost everywhere an isomorphism onto its image. LÄS MER

4. 3. Power ideals, Fröberg conjecture and Waring problems

   Författare :Alessandro Oneto; Boris Shapiro; Ralf Fröberg; Kristian Ranestad; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; power ideals; Hilbert function; fat points; Waring problem; matematik; Mathematics;

   Sammanfattning : This thesis is divided into two chapters. First, we want to study particularclasses of power ideals, with particular attention to their relation with the Fröberg conjecture on the Hilbert series of generic ideals. LÄS MER
