By Pucacco G., Rosquist K.

We examine integrable two-dimensional Hamiltonian platforms with scalar andvector potentials, admitting moment invariants that are linear or quadratic in themomenta. with regards to a linear moment invariant, we offer a few examples ofweakly integrable structures. on the subject of a quadratic moment invariant, we recoverthe classical strongly integrable structures in Cartesian and polar coordinates andprovide a few new examples of integrable structures in parabolic and ellipticalcoordinates

Even under capitalism, such rules supposedly might be useful in framing antimonopoly policy and regulating public utilities. ey might also figure in other government economic interventions and in simulating market results in nonmarket settings, as in tort settlements. ” is, I conjecture, is a clue to the ultrasubjectivist view of the concept. “Cost,” says Buchanan ( , pp. – ), “is that which the decisionmaker sacrifices or gives up when he makes a choice. ” If cost can thus be portrayed as a thoroughly subjective concept or magnitude, if no one but the individual decisionmaker (entrepreneur or manager) can know what cost is or was, and if such knowledge is ineffable and practically incommunicable, then no outside authority can reasonably impose cost-oriented rules on him.
