1. In domain theory, the sum A + B of two domains contains all elements of both domains, modified to indicate which part of the union they come from, plus a new bottom element. There are two constructor functions associated with the sum:

        inA : A -> A+B       inB : B -> A+B
        inA(a) = (0,a)             inB(b) = (1,b)

and a disassembly operation:

        case d of isa

This can be generalised to arbitrary numbers of domains.

See also smash sum, disjoint union.
