Title: On 3D defocusing cubic NLS with H^s data (s>1/2): Part 1

Time: 10:30–11:30, November 4, 2026 (Wednesday)

Inviter: Prof. Qingtang Su (MCM, CAS)

Venue: MCM510

Abstract: In this talk, we discuss the long time dynamics of 3D defocusing cubic NLS. We show global well-posedness and scattering for this model with initial data in H^s (s>1/2) Sobolev space. We will give a quick survey on this research line, then discuss the new ingredients and the main ideas.
