This paper investigates the provably total functions of fragments of first and secondorder Bounded Arithmetic. The (strongly) 3 are precisely the (strong) ] functions. The # and U are the EXPTIME [wit, poly] functions and the # definable functions of V 2 are the EXPTIME functions. We give witnessing theorems for these theories and prove conservation results 3 over S 3 and for U 2 over V 2 .
