摘要: Abstract We develop the quantum inverse scattering method for one-dimensional Hubbard model on infinite interval at zero density. The R -matrix and monodromy matrix are obtained as limits from their known counterparts finite interval. greatly simplifies in considered limit. new contains a submatrix which turns into rational of XXX -chain by an appropriate reparametrization. corresponding thus provides representation Y(su(2)) Yangian. From its determinant we obtain series mutually commuting Yangian invariant operators includes Hamiltonian.
