to Separation Logic

Separation logic is a novel system for reasoning about imperative programs.
It extends Hoare logic with enriched assertions that can describe the separa­
tion of storage and other resources concisely. The original goal of the logic
was to facilitate reasoning about shared mutable data structures, i.e., struc­
tures where updatable fields can be referenced from more than one point.
More recently, the logic has been extended to deal with shared­variable con­
currency and information hiding, and the notion of separation has proven
applicable to a wider conceptual range, where access to memory is replaced
by permission to exercise capabilities, or by knowledge of structure. In a
few years, the logic has become a significant research area, with a growing
literature produced by a variety of researchers.
1.1 An Example of the Problem
The use of shared mutable data structures is widespread in areas as diverse
