comment Properties of a specific antichain of a lattice formed by the cartesian product of finite ordered sets
From what you've written, it looks like you're maximizing over all $x$. Clearly, the best choice of $x$ is the all zeros vector, since it will have a length $n$ common prefix with every element of the poset.

This is a mixed volume of $P_D$ and $P_{-K_X}$, if that helps.

comment Categorification of the integers
You can deduce that $X^2=1$ from $X+1=0$, so perhaps it would be enough to think about $f$.

comment central charge and Calabi-Yau dimension
In the context in which I am familiar with central charge, it's a function on the objects of the category, whereas the CY-dimension is a single number associated to the category. Could you perhaps say more about how they could be one and the same thing?

@FernandoMuro: I don't grasp the meaning of your most recent comment. Could you please elaborate?
