Polyhedra and commensurability

Snapshots of modern mathematics from Oberwolfach

Polyhedra and commensurability

This snapshot introduces the notion of commensurability of polyhedra. At its bottom, this concept can be developed from constructions with paper, scissors, and glue. Starting with an elementary example, we formalize it subsequently. Finally, we discuss intrigu- ing connections with other fields of mathematics.
