Abstract
We show that the time-continuous Hamiltonian of the two-dimensional Ashkin-Teller model is that of a massive Thirring model. This implies the existence of an infinite number of conservation laws in the critical region and enables us to determine the critical exponents of the energy, crossover, and polarization operators.Keywords
