我们为群、环和代数引入了Kleisli卷积表示。我们证明,对于群和有限维代数,其表示范畴与通常的表示范畴等价,但对于环,仅能恢复底层阿贝尔群为有限秩自由的模。我们还应用Kleisli卷积表示,对Margolis--Sakurai版本的模同构问题给出了部分解答。
英文摘要
We introduce Kleisli convolution representations for groups, rings, and algebras. We show that their representation categories are equivalent to the usual ones for groups and finite-dimensional algebras, but for rings only recover modules whose underlying Abelian groups are free of finite rank. We also apply the Kleisli convolution representation to provide a partial answer to the Margolis--Sakurai version of the modular isomorphism problem: If $G$ is a finite $p$-group with $D_3(G)=1$ and $\gcd(m,c_G!)=1$, then $\mathbb F_{p^m}G\cong\mathbb F_{p^m}H$ implies $G\cong H$, where $c_G$ is the number of geometric connected components of $\mathrm{Aut}(\overline{\mathbb F}_pG)$.
