Re: Gil Kalai • Pivotal Variables

Just a tangential association with respect to logical influence and pivotability.  I have been exploring questions related to pivotal variables (“Differences that Make a Difference” or “Difference In ⟹ Difference Out”) via logical analogues of partial and total differentials.

For example, letting the partial differential operator sends a function with fiber to a function whose fiber consists of all the places where a change in the value of makes a change in the value of
