WebSep 8, 2024 · A predicate M (x,y) is partially decidable if the function f given by " f (x,y) = 1 (if M (x,y) holds), f (x,y) = undefined (otherwise) " is computable. Thm. If M (x,y) is partially decidable, then so is the predicate ∃yM (x,y). proof. Take a decidable predicate R (x,y,z) such that M (x,y) iff ∃zR (x,y,z). Then... I can not imagine the R (x,y,z)...
