AI总结:

本文提出有限范畴代数的伽罗瓦阿尔佩林权重猜想,将其转化为有限群问题,并针对EI范畴提出块级猜想。

摘要:

设p为素数,k为F_p的代数闭包,Γ为Gal(k/F_p)。令C为有限范畴,O_C为由Linckelmann定义的p-轨道范畴。本文提出有限范畴代数的伽罗瓦阿尔佩林权重猜想,断言存在一个Γ×Aut(C)-equivariant双射,将kC模块的同构类与kO_C的权重集对应。将有限范畴的GAWC转化为有限群问题。对于EI范畴,将kO_C的权重按kC的块划分,并提出块级伽罗瓦阿尔佩林权重猜想,将其转化为有限群问题。

英文摘要:

Let $p$ be a prime, $k$ an algebraic closure of $\mathbb{F}_p$ and $Γ$ the Galois group ${\rm Gal}(k/\mathbb{F}_p)$. Let $\mathcal{C}$ be a finite category and $\mathcal{O}_{\mathcal{C}}$ the $p$-orbit category of $\mathcal{C}$ defined by Linckelmann. We formulate a version of the Galois Alperin weight conjecture (GAWC) for finite category algebras stating that there exists a $Γ\times {\rm Aut}(\mathcal{C})$-equivariant bijection between the set of isomorphism classes of simple $k\mathcal{C}$-modules and that of the weights of $k\mathcal{O}_{\mathcal{C}}$. We reduce the GAWC for finite categories to finite groups. For $\mathcal{C}$ an EI-category, we give a partition of weights of $k\mathcal{O}_{\mathcal{C}}$ with respect to blocks of $k\mathcal{C}$ and then formulate a blockwise Galois Alperin weight conjecture (BGAWC) for $\mathcal{C}$. Similarly, we reduce the BGAWC for finite EI-categories to finite groups.
