On preservation of relative resolutions for poset representations
Toshitaka Aoki, Shunsuke Tada
The concept of Galois connections (i.e., adjoint pairs between posets) is ubiquitous in mathematics. In representation theory, it is interesting because it naturally induces the ad…

Mutation of Brauer configuration algebras
Toshitaka Aoki, Yingying Zhang
For Brauer graph algebras, tilting mutation is compatible with flip of Brauer graphs. The aim of this paper is to generalize this result to the class of Brauer configuration algebr…
