Trace Anomalies and Cocycles of Weyl and Diffeomorphisms Groups
D. R. Karakhanyan, R. P. Manvelyan, R. L. Mkrtchyan
The general structure of trace anomaly, suggested recently by Deser and Shwimmer, is argued to be the consequence of the Wess-Zumino consistency condition. The response of partitio…
Algebra of potentials of the volume-preserving vector fields
R. L. Mkrtchyan
The algebra of volume-preserving vector fields is considered. The potentials for that fields are introduced, and induced algebra of potentials is considered. It is shown, that this…
Geometrical action for algebra as a reduced symplectic Chern-Simons theory
R. P. Manvelyan, R. L. Mkrtchyan
The geometric action on a certain orbit of the group of the area-preserving diffeomorphisms is considered, and it is shown, that it coincides with a special reduction of the three-…
Area-preserving structure of 2d-gravity
D. R. Karakhanyan, R. P. Manvelyan, R. L. Mkrtchyan
The effective action for 2d-gravity with manifest area-preserving invariance is obtained in the flat and in the general gravitational background. The cocyclic properties of the las…
