    • Dominance and Transmissions in Supertropical Valuation Theory 

      [OWP-2011-07] Izhakian, Zur; Knebusch, Manfred; Rowen, Louis (Mathematisches Forschungsinstitut Oberwolfach, 2011)
      This paper is a sequel of [IKR1], where we defined supervaluations on a commutative ring $R$ and studied a dominance relation $\Phi >= v$ between supervaluations $\varphi$ and $\upsilon$ on $R$, aiming at an enrichment of ...

    • Some Combinatorial Identities Related to Commuting Varieties and Hilbert Schemes 

      [OWP-2011-02] Bellamy, Gwyn; Ginzburg, Victor (Mathematisches Forschungsinstitut Oberwolfach, 2011)
      In this article we explore some of the combinatorial consequences of recent results relating the isospectral commuting variety and the Hilbert scheme of points in the plane.

    • The T-Graph of a Multigraded Hilbert Scheme 

      [OWP-2011-34] Hering, Milena; Maclagan, Diane (Mathematisches Forschungsinstitut Oberwolfach, 2011)
      The $T$-graph of a multigraded Hilbert scheme records the zero and one-dimensional orbits of the $T=(K^*)^n$ action on the Hilbert scheme induced from the $T$-action on $\mathbb{A}^n$. It has vertices the $T$-fixed points, ...
