Jian Liu's homepage Welcome to Jian Liu (刘剑)’s Homepage！ Email: firstname.lastname@example.org About me I am a postdoc in Mathematics at the Shanghai Jiao Tong University(July 2021--). My postdoc mentor is Prof. Pu Zhang. I finished my PhD in Mathematics at the University of Science and Technology of China (September 2016--June 2021 ). From August 15 2019 to Ocotber 9 2020, I visited the University of Utah. My advisors were Prof. Xiao-Wu Chen and Prof. Srikanth Iyengar. My research interests are derived categories, commutative algebras and representation theory of finite dimensional algebras. Here is my English CV (Chinese CV 中文简历). Publications 4. "Exceptional complete intersection maps of local rings" with Srikanth Iyengar, Janina Letz and Josh Pollitz. arXiv version 3. "A partial converse ghost lemma for the derived category of a commutative noetherian ring" with Josh Pollitz. arXiv version 2. "Singular equivalences induced by bimodules and quadratic monomial algebras" with Xiao-Wu Chen and Ren Wang. arXiv version 1. "Duality and symmetry of complexity over complete intersections via exterior homology" with Josh Pollitz, Proceedings of the AMS, 2021.
