Abstract: We define the Lagrangians in the momentum space and in mixed position-momentum spaces. In terms of the so-defined Lagrangians, the actions and the propagators are directly defined in the spaces, not as the Fourier transforms of their counterparts in the configuration space as previously known in the literature.
