Before the MATH+ Friday Colloquium by Prof. Kathryn Hess (abstract, video recording)

Due to the current situation, the talk takes place **online**, via zoom. The meeting link has been sent out via the usual mailing lists; please contact the organisers if you have not received the email and would like to join the talk.

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.
