Complex tropical currents
Résumé :
I will briefly explain tropical currents, and will address their
extremality, intersection theory, and approximation problems. I will
discuss how in joint work with June Huh, we constructed an example of
a non-approximable current, which, in turn, refutes a stronger version
of the Hodge conjecture.
