Informal Friday Seminar -- Combinatorial Hodge theory

Alan Stapledon, University of Sydney


Informal Friday Seminar, 8th May 2026


9 am – 11 am, SMRI Seminar Room (A12 Macleay Room 301)


Abstract: The Kähler package is being delivered to more and more households throughout the world. Inspired by geometry, its contents help build a bridge between combinatorics and commutative algebra. In this talk, we’ll unpack the package and see some of what it can do—from motivating the definition of Lorentzian polynomials to applications involving Bruhat posets of Coxeter groups and matroids.

The Informal Friday Seminar is a space where members of our research group can explain interesting things to each other in a casual setting. The rules of the seminar are the following:

  1. Any question/additional explanation from the audience is allowed.
  2. Ego out the window.
  3. Examples, examples, examples.

    4. The seminar is intended to be conversational, so come ready to engage. If you choose to give an IFS talk, it's important to know that part of the IFS philosophy is that learning is not linear. In other words, it if perfectly acceptable to give a talk that is a prerequisite for a talk that already happened. For IFS updates, please see the IFS website
