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…

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…
