Abstract


The minimal system of the connective of realization – T. Jarmużek and A. Pietruszczak’s MR– is examined. The single-index rule is defined. Then it is claimed that if a single– index rule non-derivable in MR is derivable in a strengthening of MR, then the strengthening is inconsistent. This property may be called the single-index maximality.


Keywords
