Kirillov polynomials for the exceptional Lie algebra $\mathfrak g_2$

Representation Theory 2025-02-11 v1

Abstract

As part of the development of the orbit method, Kirillov has counted the number of strictly upper triangular matrices with coefficients in a finite field of qq elements and fixed Jordan type. One obtains polynomials with respect to qq with many interesting properties and close relation to type A representation theory. In the present work we develop the corresponding theory for the exceptional Lie algebra g2\mathfrak g_2. In particular, we show that the leading coefficient can be expressed in terms of the Springer correspondence.
