| Outline of Final Research Achievements |
Random plane partition or melting crystal model was a topic in the branch of combinatorics. However, it has been found surprising relations with other branches in modern mathematical physics, such as the Seiberg-Witten theory of supersymmetric gauge theories, the Gromov-Witten theory and the mirror symmetry of Calabi-Yau 3-folds. The model has been also studied from the integrable system viewpoint. We further elucidate integrable structure of melting crystal models, using quantum torus symmetry. All genus open string amplitudes on closed topological vertex are computed in a closed form, and thereby the underlying quantum curve is obtained. It turns out to be expressed as the q-difference operator which is a q-analogue of the Kac-Schwarz operator of random matrix or 2-dimensional quantum gravity. By giving a generalization of the shift symmetry of quantum torus, the relation between three-partition Hodge integral and random skew plane partition is derived.
