Ruelle Zeta Function

Abstract We propose a field-theoretic interpretation of Ruelle zeta function and show how it can be seen as the partition function for BF theory when an unusual gauge-fixing condition on contact manifolds is imposed. This suggests an alternative rephrasing of a conjecture due to Fried on the equivalence between Ruelle zeta function and analytic torsion, in terms of homotopies of Lagrangian submanifolds.

Additional Field

The soft breaking of gauge or other symmetries is the typical Quantum Field Theory phenomenon. In many cases one can apply the Stückelberg procedure, which means introducing some additional field (or fields) and restore the gauge symmetry. The original softly broken theory corresponds to a particular choice of the gauge fixing condition. In this paper we use this scheme for performing quantum calculations for fermion-torsion theory, softly broken by the torsion mass in arbitrary curved spacetime.

Insight Into

The 5-dimensional Projective Unified Field Theory (PUFT) elaborated and further developed by the author since 1957 is a geometrical semi-unified field theory restricting to gravitation, electromagnetism and scalarism. Up till now the substrate (matter) was described on a 5-dimensional phenomenological continuum mechanics. But it proved rather important to investigate the Klein–Gordon field and the Dirac field within this 5-dimensional concept of PUFT in order to get a better insight into some relationships of continuum mechanics mentioned, particularly with respect to cosmology.
