Foundations of paraconsistent resolution
An extended first-order predicate sequent calculus PLK with two kinds of negation is introduced as a basis of a new resolution calculus PRC (paraconsistent resolution calculus) for handling the property of paraconsistency. Herbrand theorem, completeness theorem (with respect to a classical-like semantics) and cut-elimination theorem are proved for PLK. The correspondence between PLK and PRC is shown by using a faithful embedding of PLK into the sequent calculus LK for classical logic.
