摘要
Complicated problems are often solved by simplification into more manageable abstract problems, the solution of which yields information about the original problem. The proposed theory lays a foundation for such a technique to solve `no-solution' problems in logic programming. The new theory is based on the concept of a homomorphism, which maps a concrete logic program into an abstract one. A homomorphism theorem establishes a relationship between the declarative semantics of such programs, which is used to prove the correctness of the proposed abstraction method for `no-solution' problems.
