Several ways to apply a (multivalued) multiargument function to a family of filters
Problem Let
be an indexed family of filters on sets. Which of the below items are always pairwise equal?

1. The funcoid corresponding to this function (considered as a single argument function on indexed families) applied to the reloidal product of filters .
2. The funcoid corresponding to this function (considered as a single argument function on indexed families) applied to the starred reloidal product of filters .
3. .

There was an error in the problem statement
I did an error in the problem statement (corrected). We need to consider the upgraded staroid, not just staroid.
