Abstract
We have calculated the nondissipative electrical and thermal currents carried essentially by the edge states in a two-dimensional ideal sample in a quantizing magnetic field. Expressions for the thermopower and thermal conductivity are obtained. The Lorenz number oscillates, as a function of the chemical potential, about the standard value. Effects of disorder are briefly examined.Keywords
