This project is an implementation for some of the data structures of Iris in Lean. While the ultimate goal of the project is to support lean-iris with a fully-fledged Iris implementation, the current target is to mechanize enough of the foundations to instantiate the frontend with upred.

This project is a work in progress

The main mechanized results so far:

• Semi-bundled hierarchy for (C)OFE
  • Nonexpansive and contractive maps
• OFE instances:
  • OFE on (bundled) nonexpansive maps
  • discreteO, laterO, leibnizO, prodO
• Bundled (C)OFE:
  • The category of (C)OFE and nonexpansive maps
    • The category OFE is cartesian closed
  • A definition for oFunctor
• Fixpoint of contractive maps

Future steps are described in Eileen: A plan for Iris in Lean.
