报告内容简介：
I shall give a brief introduction to the theory of quantum gravity at Lifshitz fixed points, proposed recently (2009) by Petro Horava, the so-called Horava-Lifshitz theory of quantum gravity. Then, I state clearly its major challenges in its original carnation, and show how they might be resolved in two different approaches with an enlarged local U(1) symmetry, one is with the projectability condition, and the other is without. The inclusion of an U(1) symmetry makes the theory have the same degree of freedom as that of general relativity, i.e., only massless spin-2 gravitons exist. Finally, I shall present some concluding remarks (if there is any), and point out some future work.
