    摘要:This short course is an introduction of Thurston's earthquake flow on Teichmuller space. Outline of the course: (1) Measured geodesic laminations on hyperbolic surfaces and Thurston's construction of earthquake. (2) Convexity of earthquake and the proof of Nielsen realization theorem. (3) Representation of earthquake in shearing coordinates.  (4) Ergodicity of earthquake flow on moduli space.

    短课:Quantum invariants and volume conjectures(5小时)

    讲课人:杨田(斯坦福大学)

    地点:苏州大学本部校区览秀楼一楼学术报告厅

    摘要:In this series of lectures, I will introduce two of the most important quantum invariants, the colored Jones polynomials of knots and the Turaev-Viro invariants of 3-manifolds, and talk about the volume conjectures relating them to the (hyperbolic) geometry of the knots and manifolds. Roughly speaking, the volume conjectures predict that the asymptotic behavior of the quantum invariants mentioned above determines some classical invariants of the knot/3-manifold, such as the hyperbolic volume. My goal is to convince you that these conjectures are promising, interesting, and maybe approachable. (A working knowledge of hyperbolic geometry and knot/3-manifold theory is very helpful, but not required.)
