comment Bogomolov-Beauville-Fujiki form, algebraically
I wonder if a purely algebraic definition of $q$ is possible (just like existence of Hodge decomposition on algebraic de Rham cohomology can be proved by the use of Leschetz principle, but there is an algebraic proof of this fact due to Deligne and Illusie). Of course it is interesting to know if the fact is true in positive characteristic.

comment Condition on moment polytope for a toric manifold to be Fano
what does it mean for a symplectic manifold to be Fano? or do you want tell if it is Fano for some kahler metric compatible with the symplectic structure?

comment discrete valuation ring and ring of witt vectors
Any witt ring is unramified over Z_p, so I would guess no.
