Lie-admissible structure of classical field theory
In this paper we summarize Santilli's Lie-admissible approach to Newtonian mechanics with particular reference to: (a) its direct universality; (b) its geometrical structure; and (c) its form-invariance under arbitrary transformations of the local variables. We then initiate the extension of this approach to field theory. The main result consists of a theorem of direct universality of the Lie-admissible equations in classical field theory. The main result consists of a theorem of direct universality of the Lie-admissible equations in classical field theory. This theorem states that in some arbitrary function space the most general possible quasi-linear system of differential equations of second order in time can always be reduced to an equivalent first-order form for which the brackets of the time-evolution law characterize a Lie-admissible algebra. The geometrical character of this algebraic setting is shown to be a field theoretical extension of Santilli's symplectic-admissible two-forms. Furthermore we prove that, as for the Newtonian case, this Lie-admissible and symplectic-admissible approach to field theory is form-invariant under arbitrary transformations. We than enter into a number of illustrative examples, with particular reference to the non-conservative extension of conventional equations.
