Coding-Logic Correspondence: Turning Information and Communication Networks into Logical Formulae via Hypergraph Heyting Algebra

We propose using confusion hypergraph (hyperconfusion) as a model of information.

In contrast to the conventional approach using random variables, we can now perform conjunction, disjunction and implication of information, forming a Heyting algebra.

Using the connection between Heyting algebra and intuitionistic logic, we can express the requirements of a communication network (e.g., network coding, index coding, Slepian-Wolf coding) as a logical formula, allowing us to use the hypergraph Heyting algebra to directly compute the optimal coding scheme.

The optimal communication cost is simply given by the entropy of the hypergraph (within a logarithmic gap).

This gives a surprising correspondence between coding settings and logical formulae, similar to the Curry-Howard correspondence between computer programs and proofs.
