Hitchin-Ngô Lab Seminar - Stability conditions for coherent systems on integral curves
Speaker: Marcos Jardim (Unicamp, Campinas)Date: Friday, 18 September 2026 - 11:30-12:30Place: Aula Naranja, ICMAT
Abstract:
We present stability conditions for the category of coherent systems on an integral curve. We define a three-parameter family of pre-stability conditions in its derived category using tilting, and then investigate when these conditions qualify as stability conditions. Additionally, we examine the semistability of specific objects under these conditions, namely: torsion, free, and complete tilted systems, without relying on the support property. Joint work with Leonardo Roa-Leguizamón and Renato Vidal Martins.
