Chapter Chapter 10 in Simple Relation Algebras, 2017, pp 411-481 from Springer

Abstract: Abstract We now describe a way of inserting new elements into a given simple relation algebra 𝔅 $$\mathfrak{B}$$ . The location of the insertion is determined by a reflexive equivalence element e, while the blueprint for the insertion is determined by a relation algebra ℭ $$\mathfrak{C}$$ . The portion of 𝔅 $$\mathfrak{B}$$ that is below e—which is just the relativization 𝔅 ( e ) $$\mathfrak{B}(e)$$ —is enlarged by adjoining copies of the elements of ℭ $$\mathfrak{C}$$ (see Figure 10.1).
