Abstract
Mundici considered the question of whether the interpolant of two propositional formulas of the form $F ightarrow G$ can always have a short circuit description, and showed that if this is the case then every problem in NP $cap$ co-NP would have polynomial size circuits. In this note we observe further consequences of the interpolant having short circuit descriptions, namely that UP $subseteq$ P$/$poly, and that every single valued NP function has a total extension in FP$/$poly. We also relate this question with other Complexity Theory assumptions.
