Abstract :
Two Lie algebras are constructed from which establish two non-isospectral problems. By solving the discrete zero curvature equations, two kinds of non-isospectral integrable couplings of the Toda lattice hierarchy are presented. Meanwhile, the recurrence operators of integrable couplings are obtained.
