dc.descriptionIn this paper we are presenting the theory of balance equations of the Continuum Thermodynamics (balance systems) in a geometrical form using Poincare-Cartan formalism of the Multisymplectic Field Theory. A constitutive relation $\mathcal{C}$ of a balance system $B_{C}$ is realized as a mapping between a (partial) 1-jet bundle of the configurational bundle $π:Y\to X$ and the dual bundle similar to the Legendre mapping of the Lagrangian Field Theory. Invariant (variational) form of the balance system $B_{C}$ is presented in three different forms and the space of admissible variations is defined and studied. Action of automorphisms of the bundle $π$ on the constitutive mappings $C$ is studied and it is shown that the symmetry group $Sym(C)$ of the constitutive relation $C$ acts on the space of solutions of the balance system $B_{C}$. Suitable version of Noether Theorem for an action of a symmetry group is presented with the usage of conventional multimomentum mapping. Finally, the geometrical (bundle) picture of the Rational Extended Thermodynamics in terms of Lagrange-Liu fields is developed and the entropy principle is shown to be equivalent to the holonomicy of the current component of the constitutive section.
dc.descriptionNew material was added in Sec.10,11, Appendix IV, some typo were corrected, description of secondary balance laws was transfered to the second part of this work
