Outline of Final Research Achievements

For any compact connected oriented surface, we formulated a Kashiwara-Vergne problem associated with a fixed marking of the fundamental group and a fixed framing of the tangent bundle, and proved that the framed Turaev cobracket has a formal description. In particular, the constraint of the Johnson image coming from the framed Turaev cobracket equals that of the Enomoto-Satoh trace. On the other hand, any group-like expansion inducing the formal description of the Goldman bracket is conjugate to a special/symplectic expansion. These results are joint works with A. Alekseev, F. Naef, a collaborator Y.Kuno and the principal investigator N. Kawazumi.
