# Symposium on advances in semi-classical methods in mathematics and physics

2016-10-19

On 19 October 2016 I give a talk on Fractional Hamiltonian Monodromy and Circle Actions at the Symposium on advances in semi-classical methods in mathematics and physics. The symposium takes place in Groningen to honor H. J. Groenewold's seminal 1946 paper On the principles of elementary quantum mechanics and the 70 years since its publication.
