A conical approximation of constant scalar curvature K\”{a}hler metrics of Poincar\’{e} type and log K-semistability

Abstract: Guenancia proved that a K\”{a}hler-Einstein metric of Poincar\’{e} type is the limit of a sequence of K\”{a}hler-Einstein metrics with cone singularities along a smooth divisor. In this talk, I will explain the recent result which is an analogue of Guenancia’s result for constant scalar curvature K\”{a}hler metrics. In addition, I will explain that constant scalar curvature K\”{a}hler metrics of Poincar\’{e} type implies log K-semistability with angle 0.
