Natural deduction for intuitionistic linear logic
by A.S. Troelstra
The paper deals with two versions of the fragment with unit, tensor,
linear implication and storage operator (the exponential !) of
intuitionistic linear logic. The first version, ILL, appears in a
paper by Benton, Bierman, Hyland and de Paiva; the second one, ILLP,
is described in this paper. ILL has a contraction rule and an
introduction rule !I for the exponential; in ILLP, instead of a
contraction rule, multiple occurrences of labels for assumptions are
permitted under certain conditions; moreover, there is a different
introduction rule for the exponential, !I+, which is closer in spirit
to the necessitation rule for the normalizable version of S4 discussed
by Prawitz in his monograph ``Natural Deduction''.
It is relatively easy to adapt Prawitz's treatment of natural
deduction for intuitionistic logic to ILLP; in particular one can
formulate a notion of strong validity (as in Prawitz's ``Ideas and
Results in Proof Theory'') permitting a proof of strong normalization.
The conversion rules for ILL explicitly mentioned in the paper by
Benton et. al. do not suffice for normal forms with subformula
property, but we can show that this can be remedied by addition of a
single conversion rule.
ILLP also suggests the study of a class of categorical models, more
special than the class introduced by Benton et. al.
