The workshop aims at reviewing the recent decomposition theorem for singular varieties with trivial canonical class. This result is the culmination of efforts of a number of researchers and this workshop brings together most researchers which contributed to the proof of this result. We will also have some talks on the geometry of hyperkähler varieties. 

The virtual workshop consist of ten talks and two online sessions. Five of the talks are original from the Summer School on Foliations and Algebraic Geometry, which took place at Institut Fourier, Grenoble in from June-July 2019 . The other five talks were recorded specially for the virtual workshop. we have host 2 online sessions with the speakers of the conference with the possibility of online intervention by the registered participants of the workshop.

Below, one possible natural order to watch the nine lectures that discuss the decomposition theorem.

1. Beauville. The decomposition theorem: the smooth case
2. Greb. Structure theory for singular varieties with trivial canonical divisor
3. Guenancia. A decomposition theorem for singular spaces with trivial canonical class (part 1)
4. Guenancia. A decomposition theorem for singular spaces with trivial canonical class (part 2)
5. Guenancia. Holonomy of singular Ricci-flat metrics
6. Höring. A decomposition theorem for singular spaces with trivial canonical class (part 3)
7. Druel. A decomposition theorem for singular spaces with trivial canonical class (part 4)
8. Druel. A decomposition theorem for singular spaces with trivial canonical class (part 5)
9. Druel. A splitting theorem
