| Outline of Final Research Achievements |
In order to understand various phenomena similar to moonshine in a uniform manner, we have considered several problems related to them. Among others, in a joint work with Maruoka and Shimakura on vertex operator algebras having large symmetries, we have classified those with minimal conformal weight one, and obtained that the simple Lie algebras belonging to Deligne exceptional series arise. We have also considered the Hilbert series of minimal nilpotent orbits of simple Lie algebrasin a joint work with A.P. Veselov and obtained a universal formula expressing the Hilbert series and the degree of the adjoint variety.
