| Outline of Final Research Achievements |
We clarified several properties of the phase space structures of the tropical periodic Toda lattice. This model is defined as a tropical limit of the discrete periodic Toda lattice, a variation of the Toda lattice which is one of the most famous models in the field of classical integrable systems. Especially, we proved that the Young diagrams defined through the Lax representation of the discrete periodic Toda lattice coincide with the Young diagrams defined as continuous limits of the corresponding diagrams defined in the combinatorial theory of the Bethe ansatz of the quantum spin chains. In addition, during a process of widening the author’s vision to find a breakthrough in future studies, we considered somehow different kind of problems in the field of integrable systems and found a new result on generalized Wick theorems in conformal field theory.
