冰箭图突变的范畴化

Categorification of ice quiver mutation

Yilin Wu

AI总结:

本文基于Pressland的带势冰箭图突变规则,证明了相关相对Ginzburg代数间存在导出等价,并给出了冻结点突变的范畴化。

摘要:

2009年,Keller和Yang通过在导出范畴间的等价性来解释箭图突变,从而将其范畴化。他们的方法基于Ginzburg的Calabi-Yau代数以及Derksen-Weyman-Zelevinsky的带势箭图突变。最近,Matthew Pressland将带势箭图突变推广到了带势冰箭图。本文证明了他的规则在相关的相对Ginzburg代数之间产生了导出等价,这些代数是Yeung的变形相对Calabi-Yau完备的特例,后者出现于Toën和Brav-Dyckerhoff的相对Calabi-Yau结构理论中。我们在Baur-King-Marsh关于Grassmannians的二聚体模型和簇范畴的工作中产生的例子上说明了我们的结果。我们还给出了在Fraser-Sherman-Bennett关于positroid簇结构的近期工作中出现的冻结点突变的范畴化。

英文摘要:

In 2009, Keller and Yang categorified quiver mutation by interpreting it in terms of equivalences between derived categories. Their approach was based on Ginzburg's Calabi-Yau algebras and on Derksen-Weyman-Zelevinsky's mutation of quivers with potential. Recently, Matthew Pressland has generalized mutation of quivers with potential to that of ice quivers with potential. In this paper, we show that his rule yields derived equivalences between the associated relative Ginzburg algebras, which are special cases of Yeung's deformed relative Calabi-Yau completions arising in the theory of relative Calabi-Yau structures due to Toën and Brav-Dyckerhoff. We illustrate our results on examples arising in the work of Baur-King-Marsh on dimer models and cluster categories of Grassmannians. We also give a categorification of mutation at frozen vertices as it appears in recent work of Fraser-Sherman-Bennett on positroid cluster structures.
