Comparing hierarchies of total functionals

Blog Article

In this Hint Guide paper we consider two hierarchies of hereditarily total and continuous functionals over the reals based on one extensional and one intensional representation of real numbers, and we discuss under which asumptions these hierarchies coincide.This coincidense problem is Photo Frame equivalent to a statement about the topology of the Kleene-Kreisel continuous functionals.As a tool of independent interest, we show that the Kleene-Kreisel functionals may be embedded into both these hierarchies.
