....and returns a symbolic representation of O(P ) As a corollary of Theorem 5.10, we obtain the following result. Corollary 5.11. The provability of P ) G in propositional LO is decidable. In view of Prop. 3. 1, this result can be considered as an instance of the general decidability result [25] for propositional ane linear logic (i.e. linear logic with weakening) Example 5.12. We calculate the xpoint semantics in a simple case. We have an LO program P made up of ve clauses: 1: a b . ....

....fragment MALL is decidable, in fact PSPACE complete [LMSS92] but the decidability of the multiplicative exponential fragment MELL is still an open problem. For affine logic, that is, linear logic with weakening, the situation is somewhat better: the full propositional fragment LLW is decidable [Kop95a]. Here, we show that the finite phase semantics is complete for MALL and for LLW, but not for MELL. In particular, this gives a new proof of the decidability of LLW. The noncommutative case is mentioned, but not handled in detail. 1. Syntax of linear logic Roman capitals A, B stand for formulas. ....
....Say that an ideal is principal if it is of the form xM for some x 2 M , and say that it is of finite type if it is a finite union of principal ideals. Finally, say that M is noetherian if all its ideals are of finite type. We shall need the following classical result, which is also crucial in [Kop95a]: Lemma 4. Any finitely generated free commutative monoid is noetherian. Proof. Such a monoid is isomorphic to N k with addition, and an ideal of N k is a subset of N k which is upwards closed for the usual ordering. N is clearly noetherian: its ideals are empty or principal. To see that ....
