Abstract: This paper gives a characterization of the truthfunctions associated with formulas generated by one atom based on Π system.Furthermore,the detailed classificationsof Fp) are provided.

Key words: Π system, logical formula, truth function, truth degree

摘要: 以Π系统为背景,针对由单个原子生成的公式,解决了王国俊教授提出的函数决定公式的问题(VDF问题),即满足什么条件的函数可由逻辑公式导出,或逻辑公式的真值函数的特征如何;进而按照逻辑等价的关系将由单原子生成的公式集进行细致地分类;最后又给出了由单个原子生成的公式的真度分布情况。
