摘要
本文在对两个模型定义了α,β,n-扩充的基础上,利用广义EhrenfeuchtGame理论证明了T(Q)的模型可归约性,从而得到:对无限基数α,β,(α≥β>0),对于模型AαTR(Q)则存在模型BβTR(Q)使得Aα≡βB;以及任意自然数m>0,存在模型C0TR(Q),使得Aα≡m0C.
We deal with the model reducibility of the generalized theory T(Q) of modules on FCPIR, finitely communtative principle ideal ring. By Ehrenfeucht Games Method we confirmed that the model of T(Q) is reducible. That is, for infinite cardinalities α,β with αβ< 0 , and a α model A, there exists a β model B s.t. A α≡ βB; and further, for a nature number m>0, there exists a 0 model C, s.t. A α≡m 0 C.
