Abstract
We consider the 2D critical Ising model on a strip with fixed boundary conditions. It is shown that for a suitable reparametrization of the known Boltzmann weights the transfer matrix becomes a polynomial in the variable \(\csc (4u)\), being \(u\) the spectral parameter. The coefficients of this polynomial are decomposed on the fixed boundaries Temperley–Lieb Algebra by introducing a lattice version of the local integrals of motion.
