Gödel defined the min-max rule for the conjunction and disjunction in his multi-valued logic as $$ u\land v=\min\{u,v\} \quad \operatorname{and} \quad u\lor v=\max\{u,v\} $$ Łukasiewicz defined rules for the negation and implication in his multi-valued logic as $$ \neg u=1-u \quad \operatorname{and} \quad u\to v=\min\{1, 1-u+v\} $$ I'd like to know which sources (books or papers better in English) contain the above definitions. I know Gödel logics is in "Zum intuitionistischen Aussagenkalkül" (1932), but I do not have access to the paper.
Ihe min-max rule for the conjunction and disjunction is also in "Introduction to a General Theory of Elementary Propositions" by Post.
