The second class of our contributions is a pair of complete characterizations of (1) the set of orderings equivalent to a given ordering and (2) the set of GHDs compatible with some equivalent ordering  ...  Our extensions to the standard techniques are a pair of simple tests that (1) determine if two orderings of aggregation operators are equivalent and (2) determine if a GHD is compatible with a given ordering  ...  Fun with semirings: A functional pearl on the abuse of linear algebra. Recall E C = {E ∈ E|E ∩ C = ∅}.  ...
