  Abstract: Studying curvature is an important aspect of studying geometry. But most notions of curvature are only defined on manifolds, whereas many interesting metric spaces aren't manifolds. We will discuss a notion of curvature, which can be defined on a large collection of metric spaces. We will discuss properties and mention some recent results about this notion of curvature.

  Abstract: Calibrated geometry is a viewpoint in geometry for studying a manifold via distinguished classes of minimal submanifolds. We will define calibrated geometries and see connection to the study of special Lagrangian submanifolds in $\mathbb{C}^n$.
