A $Gamma$-so-ring is a structure possessing a natural partial ordering,
an infinitary partial addition and a ternary multiplication, subject to a set of axioms.
The partial functions under disjoint-domain sums and functional composition is a $Gamma$-so-ring.
In this paper we introduce the notions of subdirect product and $(phi,rho)$-product of $Gamma$-so-rings
and study $(phi,rho)$-represen...
