Seminar Room: Amphitheatre Darboux Aaron Abrams: Illustrating (with) configuration spaces A configuration space is a mathematical creation designed to capture all of the information about a system that has multiple potentially complicated and interacting parts. As a mathematician, it is easy to forget how clever, abstract, useful, and even ubiquitous this idea is. How can we illustrate these objects, and how can we use them in illustration? [No background with configuration spaces will be assumed.]

Seminar - Avoiding inessential edges

• Henry Segerman

Room: Amphitheatre Darboux I'll talk about a research project, joint work with Tejas Kalelkar and Saul Schleimer, in which we used a number of different visualization techniques. A classical result says that any two triangulations of a three-manifold with the same number of vertices are connected to each other through a sequence of local combinatorial moves (namely, 2-3 and 3-2 moves). However, for some applications we need more from our triangulations - for example that all edges are essential. This means that you cannot deform any of the edges of the triangulation into a vertex. Is the subset of essential triangulations still connected by local moves? (Yes.) The proof is very visual, mostly involving the dual structure to a triangulation, which we call a foam. We discovered that real-life soap films attached to a suitable 3D printed frame will perform the local moves when the frame is flexed. With Sabetta Matsumoto, Saul and I are working on a YouTube video exploring soap films, and our results.

Clay Lecture - Examples of useful visualization in mathematical research

• Ingrid Daubechies

Room: Amphi Hermitte Mathematicians excel at abstraction; they articulate precise mathematical properties, construct abstract objects with these properties, and study them. In this pursuit, it can be extremely helpful to build special examples and understand them thoroughly-including through visualization. The presentation will feature examples of visualization useful in mathematical research, from the experience of the speaker and others. <img src="https://i0.wp.com/mathemalchemy.org/wp-content/uploads/2022/01/wavelet-mural-mathemalchemy-art-installation.jpg?w=1000&ssl=1" alt="drawing" style="width:100%;"/> Mathemalchemy (Brona Butler)
