| الوصف: | We study Basic Arithmetic, BA introduced by W. Ruitenburg. BA is an arithmetical theory based on basic logic which is weaker than intuitionistic logic. We show that the class of the provably total recursive functions of BA is a proper sub-class of the primitive recursive functions. Three extensions of BA, called BA+U, BA_c and EBA are investigated with relation to their provably total recursive functions. It is shown that the provably total recursive functions of these three extensions of BA are exactly the primitive recursive functions. Moreover, among other things, it is shown that the well-known MRDP theorem does not hold in BA, BA+U, BA_c, but holds in EBA. |
