Central charge and universal combinations of amplitudes in two-dimensional theories away from criticality.
For a general isotropic two-dimensional theory near criticality, the universal singular free energy per correlation volume fs2 is equal to -(c12)(2-)(1-)-1, where c is the central charge of the theory at criticality, is the usual specific-heat exponent, and is defined (for >0) in terms of the...
