A detailed examination of the deconfining transition in finite-temperature (2 + 1)-dimensional U(1) lattice gauge theory is presented. The transition appears to be of the Kosterlitz-Thouless type, in agreement with the two-dimensional XY model behaviour expected from universality arguments. However, measurements of the critical exponent η of the Wilson line correlation function do not give the predicted XY value.
