Snowhite and the ω dwarves
If (I,<) is a linearly ordered set, and (di)i∈I is a sequence of dwarves indexed by I, we say that a property P (x) holds eventually if there exists i0 ∈ I such that for all j > i0 we have P (dj). Let (di)i∈I be a sequence of dwarves, all distinct. The Devil puts a hat on the head of each dwarf. Each dwarf cannot see the colour of his own hat, but receives some additional information (depending...

All these mechanisms can prod...
