摘要
MV 代数是C.C.Chang为了提供Lukasiewicz和Tarski的多值逻辑系统的完备性定理的代数证明而发明的。它通过逻辑的观点,更进一步观察MV-代数的模型论性质。在本文中,我们研究了MV 代数的逻辑性质,得出形式化的MV 代数理论在子模、同态链的并之下有所保留;我们也证明了这个形式化的理论既不完备也不模型完备。
MV-algebras were invented by C. C. Chang[1] in order to provide an algebraic proof of the completeness theorem of the infinite-valued logic of Lukasiewicz and Tarski. It seems appropriate to take a further look at the model properties of MV-algebras by a logical point of views. In this paper, we study the logical properties of MV-algebras. We proved that the formalized MV-algebras theory is preserved under submodels, homomorphisms, and unions of chains; we also proved that this formalized theory is neither complete nor model complete.
