Description
We analyse Baxter's famous T-Q equations for the XXX (XXZ) spin chain and show that, apart from its usual polynomial (trigonometric) solution, which provides the solution of Bethe ansatz equations, there also exists a second solution which should correspond to the Bethe ansatz beyond N/2. This second solution of Baxter's equation plays an essential role and together with the first one gives rise to all fusion relations. (author)
