Based on the exotic Lagrangian tori constructed in CP2
by Vianna and Galkin-Mikhalkin, we construct for each Markov
triple three monotone Lagrangian tori in the 4-ball, and for
triples with distinct entries show that these tori lie in
different...
The outer automorphism group of the free group Out(F_r) acts as
the isometry group on the deformation space of weighted graphs,
Culler-Vogtmann Outer space CV_r. The train track theory of
Bestvina-Feighn-Handel bridges studying topological...
