Seminar Details

Ultraproducts of Graphs

  • Start Date: April 8, 2026

  • Seminar Series: Graduate Combinatorics Seminar
  • Presenter(s): Danae Rupp - Rutgers University
  • Event Location: Mathematics Graduate Student Lounge -- 7th Floor | Rutgers University | Hill Center | Mathematics Department
  • Presentation Type: Stand Alone Presentation
  • Abstract:

    Ultraproducts are a very important tool in model theory, and are one of the most common model theoretic tools for proving non-model theory results. In this talk I will prove via ultraproducts that if every finite subgraph of a graph is k-colorable, then the whole graph must also be k-colorable.
