Abstract

For any operator τ, we say that #P is closed under τ in context PF ○ #P, if for every f member of #P, and for every h member of PF. h ○ τ[f] also belongs to PF ○ #P. For several operators τ on #P functions, it is shown that the closure property of #P w.r.l. τ in context PF ○ #P is closely related to the relation between P#P[1] and higher classes such as PHPP and PPPP.
