Types of quantum field thories
In physics the part of the action functional of a theory which describes the dynamics of free fields without interaction is called the kinetic action.
The Legendre transform of the kinetic action is the kinetic energy (Dirichlet energy).
action functional | kinetic action | interaction | path integral measure |
---|---|---|---|
$\exp(-S(\phi)) \cdot \mu =$ | $\exp(-(\phi, Q \phi)) \cdot$ | $\exp(I(\phi)) \cdot$ | $\mu$ |
BV differential | elliptic complex + | antibracket with interaction + | BV-Laplacian |
$d_q =$ | $Q$ + | $\{I,-\}$ + | $\hbar \Delta$ |
