Location：实验楼108

Abstract:    I will talk about the construction of complex minimal smooth surfaces S of general type with p_g(S)=0, K^2_S=7. The known examples are all bidouble covers of singular Del Pezzo surfaces. Recently, joint with YongJoo Shin, we construct a new family of examples, which are bidouble covers of certain rational elliptic surfaces.
