Periodic trivial extension algebras and fractionally Calabi-Yau algebras
A Chan, E Darpö, O Iyama, R Marczinzik - arXiv preprint arXiv:2012.11927, 2020 - arxiv.org
We study periodicity and twisted periodicity of the trivial extension algebra $ T (A) $ of a finite-
dimensional algebra $ A $. Our main results show that (twisted) periodicity of $ T (A) $ is …

The Coxeter transformation on cominuscule posets
E Yildirim - Algebras and Representation Theory, 2019 - Springer
Let J (C) be the poset of order ideals of a cominuscule poset C where C comes from two of
the three infinite families of cominuscule posets or the exceptional cases. We show that the …

The bounded derived categories of the Tamari lattices are fractionally Calabi-Yau
B Rognerud - Advances in Mathematics, 2021 - Elsevier
We prove that the bounded derived category of the incidence algebra of the Tamari lattice is
fractionally Calabi-Yau, giving a positive answer to a conjecture of Chapoton. The proof …
