We investigate Riemannian metrics on compact, non-compact and singular manifolds. On the one hand, important questions in differential geometry concern the existence and construction of (complete) metrics with specific curvature properties. On the other hand, the solution of the existence question motivates the study of the space of all such metrics. In this project we will mainly be dealing with metrics with lower scalar, Ricci and sectional curvature bounds. The goal is an improved understanding of the structure and of the topological properties of spaces and moduli spaces of such metrics.

我们研究了关于紧凑，非紧凑和奇异歧管的Riemannian指标。一方面，差异几何形状中的重要问题涉及具有特定曲率特性的（完整）指标的存在和构建。另一方面，存在问题的解决方案激发了所有这些指标空间的研究。在这个项目中，我们将主要处理标量较低，RICCI和截面曲率界限的指标。目标是对此类指标的空间和模量空间的结构和拓扑特性的改进理解。
