Hyperplane Arrangements and the Scopes Equivalence


Tao Qin, University of Sydney


Informal Friday Seminar, 29th May 2026


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


Abstract: We present Webster's approach to the Scopes equivalence, specialized to Hecke algebras and $q$-Schur algebras via hyperplane arrangements. As an application, we provide an explicit description of a special class of blocks known as RoCK blocks, recovering their classical description in terms of abacus combinatorics.

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
