Uncovering the Specific Product Rule for the Lattice of Questions
H. R. N. van Erp · arXiv (Cornell University) · 2013
We give here the specific product rule for the lattice of questions. This product rule differs from the product rule for the lattice of statements, hence the qualifier `specific'. This is because the elements in the lattice of statements are ordered by way of implication, an upper context, whereas the elements in the lattice of questions are ordered by way of relevancy, a lower context.
