Refutations in Wansing’s Logic

Abstract

A refutation system for Wansing's logicW(which is an expansion of Nelson's logic) is given. The refutation system provides an efficient decision procedure for W. The procedure consists in constructing for any normal form a finite syntactic tree with the property that the origin is non-valid if some end node is non-valid. The finite model property is also established.
