You should go the the station "Villetaneuse University" with the lines T8 (connection with lines D and M13) and T11 (connection with lines B, C and D).
From there, just follow the crowd and you should arrive at the gates of the university. Passing the security should not be too complex (but it depends on who is in charge). In case of issue, do not hesitate to call me (+33.6126.96.36.199)
Once the security passed, you will have to find the room : take first stare at your right, then right on the platform, take first stairs on your right to a building, traverse the building to take the next platform, enter the next building get down the stars at your right on half a floor, you should then be in he first floor (in the French counting with a ground floor), then take the door at your left, the seminar room is the second door on your left.
Maps and more informations (in french)
If you arrive early, come to the second floor to get a coffee, but you will have to call me to open the door.
The design of type systems with subtyping is often tricky, especially
when advanced features such as intersection and union types are added.
Difficulties arise both when specifying the subtyping relation, and
in describing algorithms to decide it.
In this talk, I'll explain how several results from the rich theory of
distributive lattices can be brought to bear on this problem. In
particular, I'll explain how a result of Cederquist and Coquand
connecting distributive lattices to sequent-style entailment relations
can be used to both specify complex subtyping relations, and to derive
straightforward decision algorithms for them.
