| contents | Using properties of Blum complexity measures and certain complexity class operators, we exhibit a total computable and non-decreasing function $t_{\mathsf{poly}}$ such that for all $k$, $Σ_k\mathsf{P} = Σ_k\mathsf{TIME}(t_{\mathsf{poly}})$, $\mathsf{BPP} = \mathsf{BPTIME}(t_{\mathsf{poly}})$, $\mathsf{RP} = \mathsf{RTIME}(t_{\mathsf{poly}})$, $\mathsf{UP} = \mathsf{UTIME}(t_{\mathsf{poly}})$, $\mathsf{PP} = \mathsf{PTIME}(t_{\mathsf{poly}})$, $\mathsf{Mod}_k\mathsf{P} = \mathsf{Mod}_k\mathsf{TIME}(t_{\mathsf{poly}})$, $\mathsf{PSPACE} = \mathsf{DSPACE}(t_{\mathsf{poly}})$, and so forth. A similar statement holds for any collection of language classes, provided that each class is definable by applying a certain complexity class operator to some Blum complexity class. |
