Spinorial Field and Lyra Geometry

چکیده
The Dirac field is studied in a Lyra space-time background by means of the classical Schwinger Variational Principle. We obtain the equations of motion, establish the conservation laws, and get a scale relation relating the energy-momentum and spin tensors. Such scale relation is an intrinsic property for matter fields in Lyra background.

متن کاملLyra Black Holes
Long ago, since 1951, Lyra proposed a modification of Riemannian geometry. Based on the Lyra's modification on Riemannian geometry, Sen and Dunn constructed a field equation which is analogous to Einstein's field equations. Further more, Sen and Dunn gave series type solution to the static vacuum field equations. Retaining only a few terms, we have shown that their solutions correspond to black...
متن کاملBianchi - I Cosmology with Magnetic Field in Lyra Geometry
A new class of Bianchi-I cosmological model with magnetic field within the frame work of Lyra geometry has been presented. Exact solutions to the field equations for the model are obtained. The physical and kinematical behaviors of the model have been discussed.
متن کاملMassless DKP field in Lyra manifold
Massless scalar and vector fields are coupled to Lyra geometry by means of Duffin-Kemmer-Petiau (DKP) theory. Using Schwinger Variational Principle, equations of motion, conservation laws and gauge symmetry are implemented. We find that the scalar field couples to the anholonomic part of the torsion tensor, and the gauge symmetry of the electromagnetic field is not breaking by the coupling with...
متن کاملPlane Symmetric Domain Wall in Lyra Geometry
In this paper general solutions are found for domain walls in Lyra geometry in the plane symmetric spacetime metric given by Taub. Expressions for the energy density and pressure of domain walls are derived in both cases of uniform and time varying displacement field β. It is also shown that the results obtained by Rahaman et al [IJMPD, 10, 735 (2001)] are particular case of our solutions. Fina...
