Conjectures of Colomo–Pronko and Lukas Riegler on antisymmetrizer determinant formulas

The conjecture concerns a determinantal expression for a related antisymmetrizer arising in the study of symmetric functions and alternating-sign-matrix enumeration. The supplied sources do not state the antisymmetrizer, its variables, or the proposed determinant explicitly, so a more precise quantified formulation cannot be recovered from them.

Progress summary

Refreshed
Claimed progress

A new preprint claims progress on one conjecture and gives a related formulation of another, but does not settle the full problem.

The problem concerns conjectures linking antisymmetrizer determinant identities with symmetric functions and alternating-sign-matrix enumeration. The recent preprint addresses conjectures attributed to Colomo–Pronko and Lukas Riegler, but its supplied metadata does not identify the contributors.

Known results

  • Aigner, Fischer, Konvalinka, Nadeau, and Tewari, 2020: proved a new antisymmetrizer-to-determinant formula and a Schur-polynomial expansion conjectured independently by two groups.
  • The same work connected these functions with refined enumeration of alternating-sign matrices.

August 2026 preprint

The preprint proves a new determinantal identity for an antisymmetrizer and uses it to claim one named conjecture, apparently the Riegler conjecture. It also formulates a related version of the Colomo–Pronko conjecture without claiming its full proof; these claims remain unverified.

Current status (as of August 2026): A claimed advance and claimed proof of one related conjecture are unverified, while the full Colomo–Pronko conjecture remains open.
