Dispersionless modified DKP hierarchy as the Yang–Baxter equation

A. Zabrodin

We show that the dispersionless version of the modified DKP hierarchy originally defined as the limit of relations for the tau-function of the Hirota-Miwa type has an equivalent reformulation as the Yang-Baxter equation for Baxter’s R-matrix of Boltzmann weights for the eight-vertex model.
