We develop a method for establishing the independence of some∑ i b( α )formulas fromS 2 i( α ). In particular, we show thatT 2 i( α )is not ∀ ∑ 2 i( α )‐conservative overS 2 i( α ). We characterize the∑ i b‐definable functions ofT 2 1as being precisely the functions definable as projections of polynomial local search (PLS) problems.
