A Note on Negation: A PCS-Completion of Semilattices

- Summary

Abstract

In the paper “Which concept lattices are pseudocomplemented?” ([GK05]) we gave a contextual characterization of pseudocomplemented concept lattices by means of the arrow relations. In this contribution we use this description to embed finite semilattices into pseudocomplemented semilattices. This process can be used to define a negation on concepts.
