p-CONSEQUENCE VERSUS q-CONSEQUENCE OPERATIONS
Szymon Frankowski · 2004
Among difierent generalisations of the ordinary propositional consequence operation at last the following two are a special interest: the so-called quasi-consequence (q-consequence) and plausible consequence (p-consequence) operations, cf.[2],[3] and [1], respectively. The paper shows the special kind of symetry between two classes of operations and takes advantage of syntactic apparatus employed for p-consequences to characterize q-consequences.
