Topological string as massive spinning particle in three dimensions
I. Yu. Karataeva, S. L. Lyakhovich, I. A. Retuntsev
A model is proposed for a classical bosonic string in Minkowski space with an action functional that includes Gauss and mean world-sheet curvature. The Lagrangian is invarian…
Unfree gauge symmetry
V. A. Abakumova, S. L. Lyakhovich
The gauge symmetry is said unfree if the gauge transformation leaves the action functional unchanged provided for the gauge parameters are constrained by the system of partial diff…
Dualisation of free fields
V. A. Abakumova, S. L. Lyakhovich
We consider the general free field theory such that system of equations of motion includes a subsystem with a special property. If the subsystem is considered by itself, it would b…
Global conserved quantities and unfree gauge symmetry
V. A. Abakumova, S. L. Lyakhovich
We consider a class of theories with unfree gauge symmetry, whose gauge parameters are restricted by differential equations. We demonstrate that such theories admit global conserve…
Gauge symmetry of linearised Nordström gravity and the dual spin two field theory
V. A. Abakumova, Daniel Frolovsky, Hans-Christian Herbig +1
The field equations are proposed for the third rank tensor field with the hook Young diagram. The equations describe the irreducible spin two massless representation in any $d\geq…
Gauge symmetry of unimodular gravity in Hamiltonian formalism
I. Yu. Karataeva, S. L. Lyakhovich
We work out the description of the gauge symmetry of unimodular gravity in the constrained Hamiltonian formalism. In particular, we demonstrate how the transversality conditions re…
