Harmonic Torsion of Algebraic Generalized Ricci Solitons and the Structure of Solvable Extensions
Year: 2026
Type: preprint
Abstract: We prove harmonicity for nonshrinking algebraic generalized Ricci solitons and for all algebraic generalized Ricci solitons on solvable Lie algebras. In the solvable setting, we characterize expanding solitons by normal extensions of generalized nilsolitons, and derive a sharp rank bound.
