Query: Tropical spectral curves, Fay's trisecant identity, and generalized
  ultradiscrete Toda lattice   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).
