| Outline of Final Research Achievements |
Principal investigator Okado constructed, with Schilling and Sakamoto, a bijection between highest weight paths and rigged configurations for type D in full generality, and thereby settled the X=M conjecture in a combinatorial way. Nakanishi studied, with his collaborators, the cluster algebra from the aspect of quantum integrable systems and clarified the periodicity, dilogarithm identities, the relation between exact WKB analysis and mutation, etc. Although it was not included in the purposes of this project in the beginning of the project period, Kuniba started the study of 3-dimensional quantum integrable systems. Later, together with Okado and other collaborators, he produced results, such as the relation between quantum coordinate rings and PBW bases, 2-dimensional reduction of the tetrahedron equation, applications to Markovian processes.
