Negative Calabi-Yau discrete cluster categories via Nakayama representations and persistence theory
math.RT 2025-08 unverdicted novelty 7.0 of 10

The paper constructs infinite discrete Nakayama representations via persistence theory and stabilizes them into negative Calabi-Yau versions of Igusa-Todorov discrete cluster categories of type A, with geometric model...
