1. On the Works of Chiu-Chu Melissa Liu Kefeng Liu

2. Chiu-Chu Melissa Liu ◆ Born in Taiwan. ◆ PhD, Harvard University in 2002. ◆ Junior Fellow at Harvard from 2002 to 2005. ◆ Associate professor at Northwestern University and Columbia University.

3. Research Fields ◆ Mathematical problems from theoretical physics related to algebraic geometry, differential geometry, symplectic geometry and topology. She is one of major young leaders in these fields. ◆ In just five years of getting her PhD, Chiu-Chu M. Liu has done several fundamental and influential works on several different topics, some of them are truly landmarks in the subjects.

4. Foundations of Open Gromov- Witten Invariants ◆ Definition of open Gromov-Witten invariants, in the presence of a circle action. It covers many examples arising in Chern-Simons string duality. ◆ This is a major breakthrough in the subject.

5. The Marino-Vafa Conjecture and Mathematical Theory of Topological Vertex ◆ Proof of the famous Marino-Vafa conjecture with many corollaries. ◆ Mathematical foundation of the theory of topological vertex. ◆ Leading to many striking formulas for moduli spaces of Riemann surfaces and Gromov-Witten invariants of toric Calabi-Yau.

6. Positivity of Quasi-local Mass ◆ Proposal of new definitions of quasi-local energy and quasi-local angular momentums, proof of the positivity of quasi-local energy. ◆ Major advance in the field of general relativity.

7. Moduli Spaces of Yang-Mills Connections on Non-orientable Riemann Surfaces ◆ Extension of the fundamental works of Atiyah- Bott on moduli spaces of stable bundles to non-orientable Riemann surfaces.

8. Summary ◆ Chiu-Chu M. Liu has made fundamental contributions to several major fields of mathematics and theoretical physics. ◆ She fully deserves the distinguished Morningside Award.
