Abstract
We compute the local integrals of motions of the classical limit of the lattice sine-Gordon system, using a geometrical interpretation of the local sine-Gordon variables. Using an analogous description of the screened local variables, we show that these integrals are in involution. We present some remarks on relations with the situation at the roots of1 and results on another latticization (linked to the principal subalgebra of
rather than the homogeneous one). Finally, we analyze a module of “screened semilocal variables,” on which the whole
acts.
