| Outline of Final Research Achievements |
A new type of orthogonal polynomial, which forms a complete set in spite of missing degrees, has been energetically studied since the discovery in 2008, and the reporters have constructed this new type of orthogonal polynomial, multi-indexed orthogonal polynomial, for fundamental polynomials. For this new type of orthogonal polynomial, the three term recurrence relation, which is the characterization of ordinary orthogonal polynomial, does not hold, and certain recurrence relations with more terms were expected. We obtain them explicitly and the creation/annihilation operators are constructed by using them. This research and research to increase the list of multi-indexed orthogonal polynomials are done by using quantum mechanical formulation and many new exactly solvable quantum mechanical models are obtained.
