On a compact Lie group, there exists a 1-paramemter family of Dirac operators which interpolates the geometric Dirac operator (Levi-Civita), algebraic Dirac operator (cubic of Kostant), and the trivial Dirac operator (used in LQG). The spectral action of this family of operators is computed for SU(2).
