Tropical spectral curves, Fay's trisecant identity, and generalized ultradiscrete Toda lattice
arXiv:1003.0057 · doi:10.1142/9789814324373_0006
Abstract
We study the generalized ultradiscrete periodic Toda lattice T(M,N) which has tropical spectral curve. We introduce a tropical analogue of Fay's trisecant identity, and apply it to construct a general solution to T(M,N).
