Re: Conceptual Graphs • Gary Zhu GZ: I’m quite confused on why people are interested in Laws of Form. What is LOF trying to do? Is it just rewriting logic or is there something more fundamental. e.g. a universal algebraic … Continue reading

## Survey of Relation Theory • 5

In this Survey of blog and wiki posts on Relation Theory, relations are viewed from the perspective of combinatorics, in other words, as a topic in discrete mathematics, with special attention to finite structures and concrete set-theoretic constructions, many of … Continue reading
