Query: Geometrization of the Lax Pair Tensors   The tensorial form of the Lax pair equations are given in a compact and
geometrically transparent form in the presence of Cartan's torsion tensor.
Three-dimensional spacetimes admitting Lax tensors are analyzed in detail.
Solutions to Lax tensor equations include interesting examples as separable
coordinates and the Toda lattice.
