Abstract:

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).
