Unipotent Characters

Lists all unipotent characters γ\gamma of the chosen finite reductive group G(Fq)G(\mathbb{F}_q). The table mirrors the output of UnipotentCharacters(W) in GAP3/Chevie. Each row corresponds to one character and shows:

  • γ\gamma — the character name, derived from its Harish-Chandra series.
  • Deg(γ)\mathrm{Deg}(\gamma) — the generic degree: a polynomial in qq giving the dimension of the representation of G(Fq)G(\mathbb{F}_q) for each prime power qq.
  • FakeDegree — the fake degree polynomial, recording the graded multiplicity of γ\gamma in the coinvariant algebra of the Weyl group.
  • Fr(γ)\mathrm{Fr}(\gamma) — the Frobenius eigenvalue, a root of unity determined by Lusztig's family data.
  • Label — the label of the Lusztig family to which γ\gamma belongs.
