Anomalous action functional: the action functional (in path integral quantization) is not a globally well defined function, but instead a section of a line bundle on configuration space;.

This book introduces the quantum mechanics of particles moving in curved space by employing path integrals and then using them to compute anomalies in quantum field theories. The second part deals with the application of path integrals in statistical mechanics and many-body problems treating the polaron problem, dissipative quantum systems, path integrals over ordinary and Grassmannian coherent states perturbative expansions, effective actions and quantization of gauge theories are treated as well as special applications (the worldline formalism, spin in relativistic path integrals and the derivation of anomalies by path integral methods). I was reading through my notes on the path integral quantization of bosonic string theory when a general question about path integral quantization. If this were not the case, the Finally, in a calculation of the Weyl anomaly and the critical dimension, the professor quantizes the ghost fields. If Pfaff is not isomorphic to the trivial line bundle, we say the system has a fermionic quantum anomaly. Over the space of bosonic field configurations. A problem which occured to me is that if the quantum paths are really “weighted” by the $exp( iS_p)$, it only makes sense if $mathrm{Re}(S_p) = 0$ and $mathrm{Im}(S_p)neq0$. The path integral over the fermionic variables of the standard kinetic action functional for fermions (see for instance spinors in Yang-Mills theory) has a well-defined meaning as a section of the Pfaffian line bundle of the corresponding Dirac operator.
