Silting theory under change of rings

Wassilij Gnedin

The main goal of this paper is to compare the silting theory of an $R$ -algebra $Λ$ over a Noetherian ring $R$ with that of its tensor product $Λ \otimes Γ$ with another $R$ -algebra…

Calabi-Yau properties of ribbon graph orders

Wassilij Gnedin

We pursue the order-theoretic approach to ribbon graphs initiated by Kauer and Roggenkamp. We show that any ribbon graph order is twisted $1$ -Calabi-Yau in general and $1$ -Calabi-Y…

Cohen-Macaulay modules over some non-reduced curve singularities

Igor Burban, Wassilij Gnedin

In this article, we study Cohen-Macaulay modules over non-reduced curve singularities. We prove that the rings $k [[x, y, z]] / (x y, y^{q} - z^{2})$ have tame Cohen-Macaulay representation t…
