If uniform coding (Godelization) of potentially infinite sequences of numbers can be performed in PSPACEF, then PSPACE = EXPTIME not equal EXPSPACE = 2-EXPTIME, and, for all p, we have p-EXPSPACE = P + 1-EXPTIME; if it can be performed in LINSPACEF, we also have LINSPACE = DTIME(2(cx)); the proof fails, when relativized to oracle-TM's. A by-product of this research is that PTIMEF is not closed under number-theoretic, limited, course-of-values recursion.
