On the DLR equation for the two-dimensional sine–Gordon model
The Dobrushin–Lanford–Ruelle equation is studied in a certain space of measures in the case of two-dimensional trigonometric interactions. The uniqueness theorem extending the results of Albeverio and Hoegh-Krohn [S. Albeverio and R. Hoegh-Krohn, Commun. Math. Phys. 68, 95 (1979)] is proved. The extension is obtained by the application of some …
