Separation logic was developed by O'Hearn, Reynolds, and Yang for reasoning about shared mutable data structures.

Summary

Separation logic is a formal framework created by O'Hearn, Reynolds, and Yang to make it possible to reason rigorously about programs that share and modify complex data structures like linked lists or trees. This attribution matters because it grounds the framework in its original intent: solving the verification problem that arises when multiple parts of a program read and write the same mutable data.
