| Outline of Final Research Achievements |
We classify finite simple groups having small Sylow subgroups and determine the structure of groups appearing as Sylow subgroups of those finite simple groups. Moreover, in the case where the prime is small and a Sylow group is not abelian, we determine fusion systems over such Sylow groups.
For finite simple groups appearing in the above classification with the same Sylow subgroups and the same fusion systems over them, we construct perfect isometries between the set of irreducible characters belonging to the principal blocks of them. These isometries are those defined by Broue, namely, the ordinary perfect isometries, and not generalizations of them.
