Paris, 2nd-4th December, 2019

This meeting will be centered on questions regarding algebraic
varieties equipped with the action of an algebraic group, including
invariants defined via the associated arc spaces.  It features
research talks as well as two mini-courses : the first one by Ronan
Terpereau on the classification of normal varieties with a big
action of a reductive algebraic group, and the second one by
Anne Moreau on stringy invariants of spherical varieties.
