About non-maximality of the action functional
In this work first we review some cases where the action exhibits a minimal or a saddle-point criticality for velocity-independent potentials (V(x, t)) and maximum when the potential is velocity-dependent (V(x,ẋ,t)). In the following we will use the functional (“directional”) derivative of second o...
