Discussion again with Vivek

Suppose we have fibration with singularity over torus on the A-side, and dual torus action on the B-side, can we say taking mirror is like taking fiber?

Step 0: no superpotential, no divisor. With group action. done.

Step 1: B-side add compactification to $\C^N$, and A-side add superpotential to get pair-of-pants.

Step 2: choose a GKZ chamber, then on the B-side, we kill all the strata that we don't see. And on the A-side,
