对BL^*系统进行了研究。结合Petr Hajek的观点,在BL^*系统中添加了一元逻辑连接词Δ,得到BL^*系统的一种扩张BLΔ^*系统。随后在BLΔ^*系统中提出了理论的Δ-根的概念,并对其基本性质进行了研究。最后提出了广义与集体广义Δ-MP问题,定义了上述问题在语构意义下的解,并对解的存在性进行了讨论。
Based on the basis system L^*,a schematic extension BLΔ^* is introduced by adding the unary connective △ to BL^* with the idea of Petr Hájek.The concept of △-root of theory in BLΔ^* is proposed and basic properties of △-roots are investigated.Particularly,the problems of generalized-modus ponens and collectively generalized △-modus ponens are proposed,and the syntactic solutions of them are defined and the existence of solutions is discussed.
