The logic in question is G↓ – Gödel predicate logic with the set of truth values being V↓ = {1/n | n = 1, 2, …} ∪ {0}. It is shown in [1] that the set of its tautologies is not recursively axiomatizable . We show that this set is even non-arithmetical and we prove the set of satisfiable formulas of G↓ to be non-arithmetical. In the last section we show that another important Gödel logic G↑ is arithmetical, more precisely, (...) its set of tautologies is Π2-complete. (shrink)
