系统地研究了介于经典算术之间的半经典算术理论的守恒定理。以同样的方式,我们也刻画了其他研究充分的经典公理或规则的片段类公式的守恒定理。这揭示了守恒定理相对于经典原理的算术层次的整个结构。
We systematically study conservation theorems on theories of semi-classical arithmetic, which lie in-between classical arithmetic . In the same manner, we also characterize conservation theorems for other well-studied classes of formulas by fragments of classical axioms or rules. This reveals the entire structure of conservation theorems with respect to the arithmetical hierarchy of classical principles.
