报告摘要：

    In the past ten years, the metric measure spaces with Ricci curvature bound which was proposed by Lott-Sturm-Villani, was studied by researcher from many different areas. In this talk I will introduce some recent results on the differential structure of metric measure spaces, including the non-smooth Sobolev space, Barky-Emery theory, and the notion of tangent/cotangent modules in non-smooth framework. On the metric measure spaces with curvature-dimension condition RCD (K;N), we obtain an improved Bochner inequality and propose a definition of N-dimensional Ricci tensor.
