We consider $GL(K\mid M)$-invariant integrable supersymmetric spin chains
with twisted boundary conditions and demonstrate the role of Bäcklund
transformations in solving the difference Hirota equation for eigenvalues of
their transfer matrices. We show that the nested Bethe ansatz technique is
equivalent to a chain of successive Bäcklund transformations "undressing"
the original problem to a trivial one.
Keywords:
integrable nonlinear difference equation, Bäcklund transformation, integrable supersymmetric spin chain, Bethe ansatz.
