On the Johnson homomorphisms of the automorphism groups of free groups


In this talk, we will talk about recent developments of the Andreadakis-Johnson filtrations and the Johnson homomorphisms of the automorphism groups of free groups. In particular, we will focus on the structure of the stable cokernels and the Andreadakis conjecture. Furthermore, we will talk about those topics restricted to the basis-conjugating automorphism groups of free groups.
