Time hierarchy theorem: Consequences, Overview & Sharper hierarchy theorems

In computational complexity theory, the time hierarchy theorems are important statements about time-bounded computation on Turing machines. Informally, these theorems say that given more time, a Turing machine can solve more problems. For example, there are problems that can be solved with n2 time but not n time, where n is the input length.
