PRNCL 2009 - Workshop on Proofs and Refutations in Non-Classical Logics
(affiliated with Tableaux 2009)
Call for Papers
July 6, 2009, Oslo, Norway
* There are various ways to design a refutation-based deduction
system. Deduction systems where refutations completely replace proofs
as first-class citizens, with a set of rules inductively defining
refutation trees; systems combining proof-rules and refutation
mechanisms (or criteria) which can occur at various levels of the
proof-search process; systems where provability and refutability play
dual roles, i.e., proofs and refutations are both first-class
citizens; systems where refutations are understood as mechanisms that
build counter-models: for example, semantic information is collected
and may converge to a counter-model as the search process evolves.
Such approaches are applicable to a wide range of logics like
sub-structural logics, intermediate logics and their extensions,
modal or temporal logics, even to type theory. The deduction systems
can be based on various structures/methods: sequents, tableaux,
natural deduction, connections, proof-nets, games, etc.
The aim of the workshop is to provide a forum of discussion between
researchers interested in non-classical logics in the perspective of
proof and refutation systems.
