数学科学学院学术报告 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:北京航空航天大学沙河校区报告摘要: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 ...

微分几何讨论班(2026春第6讲)题目:On Chern-minimal surfaces in a Hermitian surface报告人:许小卫 教授(中国科技大学)时间:2026年5月8日9:30-10:30地点:沙河校区主楼E806摘要:In the 1980s, S. Webster ([W-84], [W-86]) founded two beautiful formulae, which involve the geometry and topology of minimal surfaces in a Kahler surface. Later, J.G. Wolfson ([W-89]) gave some deep applications of these fo...
