Query: Lagrangian Descriptors and the Action Integral of Classical Mechanics   In this paper we bring together the method of Lagrangian descriptors and the
principle of least action, or more precisely, of stationary action, in both
deterministic and stochastic settings. In particular, we show how the action
can be used as a Lagrangian descriptor. This provides a direct connection
between Lagrangian descriptors and Hamiltonian mechanics, and we illustrate
this connection with benchmark examples.
