Add   Hamiltonian BFV-BRST quantization for the systems with unfree gauge symmetry
Authors: Abakumova, Victoria A. | Lyakhovich, Simon L.
Source: AIP Conference Proceedings. 2021. Vol. 2377. P. 090001-1-090001-5
Type: статьи в журналах
Date: 2021
Description: The BFV-BRST Hamiltonian quantization method is presented for the theories where the gauge parameters are restricted by differential equations. The general formalism is exemplified by the Maxwell-like ... More
Add   Reducible gauge symmetry versus unfree gauge symmetry in Hamiltonian formalism
Authors: Abakumova, Victoria A. | Karataeva, Inna Yu | Lyakhovich, Simon L.
Source: Nuclear physics B. 2021. Vol. 973. P. 115577 (1-30)
Type: статьи в журналах
Date: 2021
Description: The unfree gauge symmetry implies that gauge variation of the action functional vanishes provided for the gauge parameters are restricted by the differential equations. The unfree gauge symmetry is sh ... More
Add   Reducible Stueckelberg symmetry and dualities
Authors: Abakumova, Victoria A. | Lyakhovich, Simon L.
Source: Physics Letters B. 2021. Vol. 820. P. 136552 (1-6)
Type: статьи в журналах
Date: 2021
Description: We propose a general procedure for iterative inclusion of Stueckelberg fields to convert the theory into gauge system being equivalent to the original one. In so doing, we admit reducibility of the St ... More
