Conference: Topology of Arrangements with an Eye to Applications

The conference “Topology of Arrangements with an Eye to Applications” will be held at the University of Pisa, Italy, during September 1-5, 2025. This topic is of interest to a large international research community, spread across mathematical disciplines. This event aims to both disseminate recent research developments, as well as facilitate contact between emergent junior researchers and established senior members of the community. This award will increase the participation of US-based mathematicians, especially graduate students and early-career researchers. The central theme of the conference is the theory of hyperplane arrangements, with a special focus on the topological aspects of the field, the connection between arrangements and Artin groups (which witnessed striking recent developments) and applications (especially topological data analysis). A special feature of this field is its interaction with several areas of mathematics, and this blend of ideas and perspectives continues to drive significant progress in the area. As such, the conference will touch on connections to, for instance, algebraic topology, geometric group theory, algebraic and geometric combinatorics, matroid theory, algebraic geometry, and singularity theory. In addition to invited speakers, this event will include a contributed poster session and ample time for discussion to foster collaboration among participants.
