Stability and Hamiltonian BRST-invariant deformations in Podolsky's generalized electrodynamics
We study the problem of stability in Podolsky's generalized electrodynamics by constructing a series of 2-parametric bounded conserved quantities. In this way, we show that the 00-component of the energy-momentum tensors could be positive definite and therefore the higher derivative system is c...
