斜柔代数之间利用orbifolds的导等价

Derived equivalences between skew-gentle algebras using orbifolds

Claire Amiot, Thomas Brüstle

摘要:

斜温柔代数是温柔代数的斜群代数,它具有一定的$\Z_2$ -作用。本文利用Gentle代数与剖分曲面之间的双射对应关系,得到了斜Gentle代数与某些允许双覆盖的剖分Orbifold之间的双射.证明了双覆盖上的$\Z_2$ -作用与斜群代数构造的相容性。这使我们能够调查派生的等价关系之间的斜温柔代数的几何条件:我们关联到每个斜温柔代数的线领域的orbifold,并在其双重覆盖,并解释不同种类的派生等价的斜温柔代数的代数方面的同胚尊重的同伦类的线领域相关联的代数。

英文摘要:

Skew-gentle algebras are skew-group algebras of gentle algebras equipped with a certain $\Z_2$-action. Building on the bijective correspondence between gentle algebras and dissected surfaces, we obtain in this paper a bijection between skew-gentle algebras and certain dissected orbifolds that admit a double cover. We prove the compatibility of the $\Z_2$-action on the double cover with the skew-group algebra construction. This allows us to investigate the derived equivalence relation between skew-gentle algebras in geometric terms: We associate to each skew-gentle algebra a line field on the orbifold, and on its double cover, and interpret different kinds of derived equivalences of skew-gentle algebras in terms of diffeomorphisms respecting the homotopy class of the line fields associated to the algebras.
