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 de nition of N-dimensional Ricci tensor.
