Abstract:This paper studies the cancellative partial ordered extension and properties of quotient ordered homomorphisms of cancellative partially ordered semigroups(CPOS). The notion on quotient semi-pseudoorder of partially ordered semigroup(POS) is introduced. With the quotient semi-pseudoorder of CPOS and using the method of partial ordered extension of POS, the sufficient condition for extending a cancellative partial order of CPOS to another cancellative partial order is derived. It is also shown that quotient ordered homomorphism of partially ordered semigroup POS can be depicted by semi-pseudoorder σ, closed semi-pseudochain of modulo σ, quotient semi-pseudoorder, partial ordered extension of partially ordered semigroup, and cancellative partial ordered extension of CPOS. Some important conclusions are obtained.
