Given a polynomial-time algorithm, can we compute an explicit polynomial time bound just fro...
Just to observe, also in view of Carl Mummert comment, that I used very similar techniques in my POPL'08 article "The intensional content of Rice's theorem". I call "complexity clique" a class of prog …

Is simply typed lambda calculus with fixed-point combinator Turing-complete?
Damiano is right, the answer is no: it is not Turing complete.
Supposing to define natural numbers as some type (o->o)->o->o,
even with fixpoints you cannot define the predecessor (that would be
