Vz. Enolskii et M. Salerno, LAX REPRESENTATION FOR 2-PARTICLE DYNAMICS SPLITTING ON 2 TORI, Journal of physics. A, mathematical and general, 29(17), 1996, pp. 425-431
The Lax representation in terms of 2 x 2 matrices is constructed for s
eparable multiply-periodic systems splitting on two tori. Hyperellipti
c Kleinian functions and their reduction to elliptic functions are use
