Ecalle's dimorphic transportation and Brown's lifting
Hanamichi Kawamura
Brown's lifting procedure shows that one can solve the double shuffle equations modulo products from solutions of linearized ones. In this paper, we reveal that it is described in…

Ecalle's senary relation and dimorphic structures
Hanamichi Kawamura
This paper gives a completed proof of Ecalle's senary relation in the original form. As an application, we obtain another proof of the fact that the double shuffle Lie algebra inje…
