Elementary slopes of plane-wide breakout
Yann Jullian
We consider a mathematical model of the breakout game where is covered by unit square bricks everywhere except in one place. We introduce elementary blocks (particul…

An algorithm to identify automorphisms which arise from self-induced interval exchange transformations
Yann Jullian
We give an algorithm to determine if the dynamical system generated by a positive automorphism of the free group can also be generated by a self-induced interval exchange transform…

Explicit computation of the index of a positive outer automorphism of the free group
Yann Jullian
We give an algorithm for finding the index of a positive outer automorphism of the free group, and prove the algorithm exits in a finite time.
