About what?

In the talk I give a practical introduction to alpha complexes and persistent homology. Persistent homology is a formalism that enables us to compute topological features of a space at different spatial resolutions. It is often used on simplicial complexes that were constructed on point clouds. Alpha complexes are one popular way of constructing these simplicial complexes.
