The leading high-energy behavior of the sum of ladder diagrams is discussed in local and nonlocal field theories of nonpolynomial type. It is shown that the complete amplitude satisfies an integral equation of Volterra type at highenergy and in several cases it possesses Regge-behaved upper bounds.

The inverse problem of the calculus of variations is analysed in the case of Newtonian mechanics. Its connection with the question: "Does the equation of motion determine commutation relations?" raised some time ago by Wigner, is exhibited. All the Lagrangians that yield variational equations equiv
