Dirac-like Equations for Barotropic Frw Cosmologies
where a is the scale factor of the universe, ρ and p are the energy density and the pressure, respectively, of the perfect fluid of which a classical universe is usually assumed to be made of, κ = 0,±1 is the curvature index of the flat, closed, open universe, respectively, and γ is the constant adiabatic index of the cosmological fluid. Recently, Faraoni, proposed the “Riccati route” of solvin...
متن کاملOrder reductions of Lorentz - Dirac - like equations
We discuss the phenomenon of preacceleration in the light of a method of successive approximations used to construct the physical order reduction of a large class of singular equations. A simple but illustrative physical example is analyzed to get more insight into the convergence properties of the method. Short title: LETTER TO THE EDITOR
متن کاملDirac operator index and topology of lattice gauge fields
The fermionic topological charge of lattice gauge fields, given in terms of a spectral flow of the Hermitian Wilson–Dirac operator, or equivalently, as the index of Neuberger’s lattice Dirac operator, is shown to have analogous properties to Lüscher’s geometrical lattice topological charge. The main new result is that it reduces to the continuum topological charge in the classical continuum lim...
متن کاملNonlinear Dirac-like Equations and Seiberg-Witten Equations
By analysing the work of Campolattaro we argue that the second SeibergWitten equation over the Spinc4 manifold, i.e., F + ij = 〈M,SijM〉, is the generalization of the Campolattaro’s description of the electromagnetic field tensor F in the bilinear form F = ΨSΨ. It turns out that the Seiberg-Witten equations (also the perturbed Seiberg-Witten equations) can be well understood from this point of v...
متن کاملGeometric Second Order Field Equations for General Tensor Gauge Fields
Higher spin tensor gauge fields have natural gauge-invariant field equations written in terms of generalised curvatures, but these are typically of higher than second order in derivatives. We construct geometric second order field equations and actions for general higher spin boson fields, and first order ones for fermions, which are non-local but which become local on gauge-fixing, or on intro...
