Unfree gauge symmetry in the Hamiltonian formalism
V. A. Abakumova, I. Yu. Karataeva, S. L. Lyakhovich
The constrained Hamiltonian formalism is worked out for the theories where the gauge symmetry parameters are unfree, being restricted by differential equations. The Hamiltonian BFV…
Conservation laws and stability of higher derivative extended Chern-Simons
V. A. Abakumova, D. S. Kaparulin, S. L. Lyakhovich
The higher derivative field theories are notorious for the stability problems both at classical and quantum level. Classical instability is connected with unboundedness of the cano…
Stable interactions between the extended Chern-Simons theory and a charged scalar field with higher derivatives: Hamiltonian formalism
V. A. Abakumova, D. S. Kaparulin, S. L. Lyakhovich
We consider constrained multi-Hamiltonian formulation for the extended Chern-Simons theory with higher derivatives of arbitrary finite order. The order extension of the theory…
