AI 中文总结
该研究在任意特征代数闭域上,构造了广义 Dynkin 型预投射代数 $\tilde{A}_2$ 的有限维投射模范畴的三角化结构,证明其既非代数也非拓扑三角化范畴,拓展了三角化范畴的存在性结论。
AI 中文摘要
我们证明,在任意特征的任意代数闭域上,广义 Dynkin 型预投射代数 $\tilde{A}_2$ 上的有限维投射模范畴具有三角化范畴结构,该结构既非代数三角化范畴也非拓扑三角化范畴。
英文摘要
We show that, over any algebraically closed field of any characteristic, the category of finite-dimensional projective modules over the preprojective algebra of generalized Dynkin type $\mathbb{L}_2$ has a pretriangulated category structure which is neither an algebraic nor a topological triangulated category structure.
