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...
A large fraction of exoplanetary systems contain planets that
orbit very close to their host stars. With orbital periods in the
range of days to weeks, tidal forces become important and lead to
significant orbital and physical effects on the planets...
