On conformal Ricci collineations associated with the Bott connection on three-dimensional Lorentzian Lie groups

  • Published: 13 April 2026
  • This paper presents a complete classification of conformal Ricci collineations (CRCs) associated with the Bott connection on three-dimensional Lorentzian Lie groups. For each of the seven distinct classes of such groups, we derive explicit conditions under which left-invariant vector fields define CRCs, and we characterize the corresponding solution spaces. Specifically, we find that groups $ G_{1} $ and $ G_{7} $ admit rich non-trivial CRCs associated with $ \nabla^{B_{1}} $, highlighting the rich geometric structure induced by this connection.
