Research Abstract |
The Hankel transform makes a new sequence of numbers from a given sequence of numbers by computing Hankel determinants of the given numbers. In this study the Hankel transform is examined from the viewpoint of discrete integrable systems having determinant solutions which relate with combinatorial objects such as lattice paths. The results are applied to initial value problems of discrete integrable systems. Especially combinatorial expressions in terms of non-intersecting lattice paths are given to the exact solutions to the initial value problems of the discrete Toda molecules and related integrable systems. Furthermore a tiling problem of the Aztec diamond is also investigated. To the Aztec diamond theorem a new proof is exhibited by using discrete integrable systems with the help of orthogonal functions.
