  then we multiply by a logarithmic factor. Be warned that these cases are not exhaustive { for example, it is possible for f(n) to be asymptotically larger than nlog b a, but not larger by a polynomial factor (no matter how small the exponent in the polynomial is). For example, this is true when f(n) = nlog b alogn.
