Abstract
This work concerns the Edwards-Anderson Ising model of a spin ladder, in wh ich random bonds +/-J connect nearest-neighbor Ising spins. We calculate th e exact free energy of the quenched, frustrated, spin-glass-like ladder as an integral over a probability distribution P(x), the eigenfunction of a st atistical transfer matrix. Our approach takes advantage of the statistical homogeneity of the spin glass.
