    A lemma on a total function defined over the Baker-Gill-Solovay set of polynomial Turing machines

    Full text link
    If we establish that the counterexample function for P=NP, if total, overtakes all total recursive functions when extended over all Turing machines, then what happens to the same counterexample function when defined over the so-called Baker-Gill-Solovay (BGS) set of poly machines? We state and prove here a lemma that tries to answer this query.Comment: LaTe

    On a total function which overtakes all total recursive functions

    Full text link
    This paper discusses a function that is frequently presented as a simile or look-alike of the so-called ``counterexample function to P=NP,'' that is, the function that collects all first instances of a problem in NP where a poly machine incorrectly `guesses' about the instance. We state and give in full detail a crucial result on the computation of Goedel numbers for some families of poly machines.Comment: LaTe

    On the consistency of P=NPP=NP with fragments of ZFC whose own consistency strength can be measured by an ordinal assignment

    Full text link
    We formulate the P<NPP<NP hypothesis in the case of the satisfiability problem as a Π20\Pi ^0_2 sentence, out of which we can construct a partial recursive function f¬Af_{\neg A} so that f¬Af_{\neg A} is total if and only if P<NPP < NP. We then show that if f¬Af_{\neg A} is total, then it isn't T{\cal T}--provably total (where T{\cal T} is a fragment of ZFC that adequately extends PA and whose consistency is of ordinal order). Follows that the negation of P<NPP < NP, that is, P=NPP = NP, is consistent with those T{\cal T}.Comment: LaTeX, 19 pages, no figure
