Statement: shorter
Line 105:
'''Note 1.''' ''f''(''n'') is at least ''n'', since smaller functions are never time-constructible.<br>
 
'''Example.''' <math>\mathsf{DTIME}(n) \subsetneq \mathsf{DTIME} (n (\ln n)^2) </math>.
'''Example.''' There are problems solvable in time ''n''log<sup>2</sup>''n'' but not time ''n''. This follows by setting <math>f(n) = n\log n</math>, since ''n'' is in
:<math>o\left(n\log n\right).</math>
