Available to watch now, IUVSTA, in partnership with Agilent Technologies explores how magnetohydrodynamics can be formulated through a variational principle as a field theory In this webinar, ...
Causal field theories employ deterministic notions of cause and effect alongside variational formulations, whereby the dynamics of a system are derived by extremising an action functional. In ...
We give a geometric interpretation for the principle of stationary action in classical Lagrangian particle mechanics. In a nutshell, the difference of the action along a path and its variation ...
