{synonym}
A <differential one-form> $\theta$ is a smooth <section of a vector bundle> $T^*X\to X$. Its graph is its image as a section, and the projection restricts to a <diffeomorphism> onto $X$. Pullback of the <Liouville one-form> by that section equals $\theta$, making the <twisted Lagrangian graph criterion> immediate.
