A weak variant of Robinson's arithmetic Q where the binary operations of addition and multiplication are replaced by ternary relations ( not necessarily defining total crisp functions) is formulated and investigated over the mathematical fuzzy logic BL for all. Essential undecidability of this fuzzy arithmetic is proved by a careful analysis of the classical proof of essential undecidability of arithmetic.
Je formulována slabá varianta Robinsonovy aritmetiky Q s ne nutně totálními operacemi; tato teorie se vyšetruje v rámci základní matematické predikátové logiky BL. Je podán důkaz podstatné nerozhodnutelnosti této fuzzy aritmetiky.
