北航数学论坛 --微分几何讨论班（2026年春季第10讲）题目：A proof of Positive mass theorems up to dimension 19 报告人：史宇光 教授（北京大学）时间：2026年6月10日 16:00-17:00地点：沙河主E806摘要：In this talk, I will present a proof of Riemannian positive mass theorem up to dimension 19, building on a combination of toric symmetrization and the singularity blow-up technique developed in a joint wor...
tyc8722太阳集团学术报告题目：Twisted representations and fields of moduli报告人：杨天秩（Scuola Normale Superiore, Italy）时间：2026-06-03 10:30—11:30（周三上午）地点：沙河主楼E802摘要：The field of moduli of an algebraic structure — such as avariety, vector bundle, or polarization — is the smallest field over which the structure is isomorphic to all of its Galois conjugates. A field of definit...

tyc8722太阳集团学术报告 Complete proof of the Peres conjecture for contextuality via graph theory许振朋（安徽大学） 报告时间：2026年5月14日上午10：00报告地点：tyc8722太阳集团沙河校区报告摘要：A central result in the foundations of quantum mechanics is the Kochen-Specker theorem. In short, it states that quantum mechanics cannot be reconciled with classical models that are noncontextual for ideal ...

北航数学论坛Frobenius manifolds and bihamiltonian integrable hierarchies张友金 教授清华大学报告时间：2026年5月8日（星期五）下午14：00--16：00报告地点：沙河主楼E802报告摘要：The notion of Frobenius manifolds was introduced by Boris Dubrovin in the early 1990s. It has played important roles in the study of Gromov-Witten theory, singularity theory, integrable systems and some other research fields...
