Аннотация:
Lagrangian submanifolds play an important role in classical
mechanics and symplectic topology. After recalling a few
results and problems on these submanifolds, I will restrict
on the special class of real Lagrangian submanifolds, namely
the fixed point sets of anti-symplectic involutions. I hope
to convince you by many examples that this is an interesting
class, and will then discuss two criteria for a Lagrangian
to be real, that are due to Joontae Kim and Joé Brendel.
