The spectral gap of the 2-D stochastic Ising model with nearly single-spin boundary conditions
Kenneth S. Alexander
We establish upper bounds for the spectral gap of the stochastic Ising model at low temperature in an N-by-N box, with boundary conditions which are ``plus'' except for small regio…

The spectral gap of the 2-D stochastic Ising model with mixed boundary conditions
Kenneth S. Alexander, Nobuo Yoshida
We establish upper bounds for the spectral gap of the stochastic Ising model at low temperatures in an n-by-n box with boundary conditions which are not purely plus or minus; speci…
