"Barcode Decorated Merge Trees" | Department of Mathematics

Bi-College Math Colloquium

Monday, November 7, 2022 - 4:00pm

Max Planck Institute

Location

Haverford College

Hilles 109

Tea will be served at 3:30 p.m. in the foyer outside of Hilles 109.

In this talk, I am going to introduce two main tools of Topological Data Analysis: persistence barcodes and merge trees. Both of them are tools to analyze geometric data by keeping track of topological changes along a family of spaces obtained from the data. Then, I will discuss a recent construction combining both, called Barcode Decorated Merge Trees. Joint work with J. Curry, H. Hang, T. Needham and W. Mio.

Maps and Directions

We are about a 15 minute walk from the main 30th Street Station and 5 minutes from the University City Rail Station at 32nd and Spruce (=South Street & Convention Avenue). Coming from the airport by train (about 15 minutes): the University City Rail Station is the second stop after you leave the airport.

If you drive, the most convenient public parking is in the pay lot whose entrance is on 34th Street between Market and Chestnut Streets.
