A solvable extended logarithm of the Johnson homomorphism
arXiv:2202.11273
Abstract
We suggest an extension of a certain logarithm of the total Johnson map in terms of solvable Lie groups. Here, the domain of the map is extended to a subset consisting of exponential solvable elements in the mapping class group of a surface.
