    We study the Jacobi-Trudi-type determinat which is conjectured to be the q-characters of a certain, in many cases irreducible, finite-dimensional representation of the quantum affine algebra of type D_n. We obtain an expression by a positive sum over a set of tuples of paths, which is naturally translated into the one over a set of tableaux on a skew diagram.

    We study theory and applications of cluster algebras which is one of algebraic and combinatorial structure in integrable systems. We obtain the following new results and insights: derivation of dilogarithm identities in cluster algebras by classical mechanical method, systematic proofs of synchronicity phenomenon and related conjectures, derivation of the relation between cluster algebra theory and scattering diagrams in the cluster algebraic point of view, proof that any consistency relation in a cluster scattering diagram is generated by the pentagon identity among dilogarithm elements, dilogarithm identities associated to cluster scattering diagrams and their quantizations, derivation of product formula of F-polynomials.
