2+1D-sector models of curved spacetimes — •Corvin Zahn and Ute Kraus — Hildesheim University

Sector models can represent curved surfaces, spaces, and spacetimes. The basic principle is the subdivision of the surface/space/spacetime into small parts, and the approximation of each small part by a small flat part. Sector models can be used to study geometry, e.g. to determine curvature and to construct geodesics.

We present sector models of several spacetimes (with one spatial dimension suppressed) and illustrate the test for curvature components.
