| Outline of Final Research Achievements |
In this research, we mainly obtained the following results: We found that the d-complete poset being multivariable hook length poset implies the leaf poset being multivariable hook length poset. We expressed the number of the domino tilings in the Aztec rectangle with connected 2r-holes by a determinant of the matrix of size 2r whose elements are hypergeometric series. We proved a quadratic formula of hypergeometirc series which is useful for the proof of some kind of Hankel type determinants.
