Representation-tame Geiß-Leclerc-Schröer algebras and a revised GLS conjecture on root systems
Qiang Dong, Zengqiang Lin, Ming Lu +1
Using Galois covering theory and equivariant techniques, we classify all connected representation-tame Geiß--Leclerc--Schröer (GLS) algebras in terms of their defining triples $(C,…
Frobenius quotients, inflation categories and weighted projective lines
Xiao-Wu Chen, Qiang Dong, Shiquan Ruan
We propose the notion of Frobenius quotients between Frobenius exact categories. It turns out that any Frobenius quotient induces Frobenius quotients between the corresponding infl…
Tilting Objects via Recollements and -Cycles on Weighted Projective Lines
Qiang Dong, Hongxia Zhang
In this paper, we provide a new method for constructing tilting objects in a triangulated category via recollements. The -cycle approach to exceptional curve processes significa…
On two open questions for extension bundles
Qiang Dong, Shiquan Ruan
In this paper we give positive answers for two open questions on extension bundles over weighted projective lines, raised by Kussin, Lenzing and Meltzer in the paper ``Triangle sin…
