Hall induction for cotangent representations and wheel conditions (2601.00124v1)
Published 31 Dec 2025 in math.RT and math.AG
Abstract: In this short note we study the Hall induction of cotangent representations of reductive groups. We prove its torsion freeness in Borel-Moore homology. In K-theory we find an analog of wheel conditions verified by the image of restriction map to the fixed point and consider examples.
