“Joins of r.i.c.e relations and r.i.c.e complete relations”
We will show that there is a natural way to form both finite and infinite joins of subsets of a structure. We will also introduce r.i.c.e complete relations, and show that every structure has a r.i.c.e. complete relation. We will use this to define a jump operator on relations in structures.
