Query: Exponential corrections to low-temperature expansion of 2D non-abelian
  models   The thermodynamic limit of certain exponential corrections to the weak
coupling expansion of two-dimensional models is investigated. The expectation
values of operators contributing to the first order coefficient of the
low-temperature expansion of the free energy are calculated for the order
O(e^{-\beta}). They are proven to diverge logarithmically with the volume for
non-abelian models.
