报告简介:

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, Istate clearly  its major challenges in its original carnation, and show how they might be  resolved in two different approaches with an enlargedlocal U(1) symmetry, one  iswith the projectability condition,and the other iswithout. 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.
