- ItemCommuting differential operators and higher-dimensional algebraic varieties(Oberwolfach : Mathematisches Forschungsinstitut Oberwolfach, 2012) Kurke, Herbert; Osipov, Denis; Zheglov, AlexanderSeveral algebro-geometric properties of commutative rings of partial differentiall operators as well as several geometric constructions are investigated.
- ItemFormal punctured ribbons and two-dimensional local fields(Oberwolfach : Mathematisches Forschungsinstitut Oberwolfach, 2008) Kurke, Herbert; Osipov, Denis; Zheglov, AlexanderWe investigate formal ribbons on curves. Roughly speaking, formal ribbon is a family of locally linearly compact vector spaces on a curve. We establish a one-toone correspondence between formal ribbons on curves plus some geometric data and some subspaces of two-dimensional local field.
