Summary of Expertise

Jie Qing works on conformal geometry, the AdS‑CFT correspondence, and most recently in general relativity. In conformal geometry, only the angle between two vectors can be measured but not the vector’s lengths. The AdS‑CFT correspondence relates the Riemannian or pseudo-Riemannian (general relativistic) geometry on one manifold to the conformal geometry of a manifold that bounds it. AdS‑CFT has roots going back about 30 years but became very popular in the last decade due to its relevance to string theory. Qing has some of the strongest uniqueness results available in AdS/CFT for conformal spheres.

Research Interests

Jie Qing is interested in nonlinear analysis, harmonic analysis, and partial differential equations (systems) with applications to differential geometry, complex geometry and mathematical physics. More specifically Jie Qing is working in the fields of conformal geometry, partial differential equations in conformal geometry, geometric problems arising from mathematical relativity. Currently Jie Qing is interested in developing mathematical foundation for AdS/CFT correspondence proposed in the promising theory of quantum gravity in Mathematical Physics.
