Vb. Kuznetsov, SEPARATION OF VARIABLES FOR THE D-N-TYPE PERIODIC TODA LATTICE, Journal of physics. A, mathematical and general, 30(6), 1997, pp. 2127-2138
We prove separation of variables for the most general (D-n-type) perio
dic Toda lattice with a 2 x 2 Lax matrix. It is achieved by finding pr
oper normalization for the corresponding Baker-Akhiezer function. Sepa
ration of variables for all other periodic Toda lattices associated wi
th infinite series of root systems follows by taking appropriate limit
