The section on authoritative resource algebras could benefit from a slight rewriting.
Some salient points:

  • The generally presented rules for the RA are not sufficient for deriving the properties of the fractional use case
  • There are some erratas, see below

Known erratas:

  • The specifications of Exercise 8.52 do not recover the spatial isCounter predicate in the post-condition.
  • Many definition use multiple ∀ x. ∀ y. ∀ z. _ rather than the iterated ∀ x, y, z. _
  • The first RA construction uses m/n for the fragmental piece, but the generalised construction uses a/b
