Brieskorn-Pham singularities via ACM bundles on Geigle-Lenzing projective spaces

Jianmin Chen, Shiquan Ruan, Weikang Weng

We study the singularity category of the Brieskorn-Pham singularity $R=k[X_1,\dots ,X_4]/({\sum }_{i=1}^4{X}_i^{p_i})$, associated with the Geigle-Lenzing projective space $\mathbb{…
