About what?

In the world of discrete geometry, somewhere between combinatorics and geometry, Pachner moves (or bistellar flips) are an important tool to "build up" complex triangulations from more simple ones, while preserving topological properties. I will show with examples how Pachner moves pop up in old and new questions, spanning topics from combinatorics to topology.
