  1. 1. Classification of plethories in characteristic zero

    Författare :Magnus Carlson; Tilman Bauer; Lars Hesselholt; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plethories; Witt vectors; ring schemes; Mathematics; Matematik;

    Sammanfattning : We classify plethories over fields of characteristic zero, thus answering a question of Borger-Wieland and Bergman-Hausknecht. All plethories over characteristic zero fields are linear, in the sense that they are free plethories on a bialgebra. LÄS MER

  3. 2. Abelian affine group schemes, plethories, and arithmetic topology

    Sammanfattning : In Paper A we classify plethories over a field of characteristic zero. All plethories over characteristic zero fields are ``linear", in the sense that they are free plethories on a bialgebra. For the proof of this classification we need some facts from the theory of ring schemes where we extend previously known results. LÄS MER
