Re: Peirce List Discussion • Helmut Raulien

The facts about relational reducibility are relatively easy to understand and I included links to relevant discussions in my earlier survey of relation theory.

The following article discusses relational reducibility and irreducibility in general terms and gives concrete examples of reducible and irreducible triadic relations of the sort we find in mathematics and semiotics, illustrating the two types of reducibility that usually come up in these settings.

• Relation Reduction

These examples were introduced in the following articles on triadic relations and sign relations and I believe one could learn a lot from their careful consideration.

• Triadic Relations
• Sign Relations
