A refinement of the McCreight-Meyer union theorem

Abstract Using properties of Blum complexity measures and certain complexity class operators, we exhibit a total computable and non-decreasing function $$t_\textsf{poly}$$ t poly such that for all k , $$\Sigma _k\textsf{P}= \Sigma _k\textsf{TIME}(t_\textsf{poly})$$ Σ k P = Σ k TI...
