Chebyshev's theorem
From Wikipedia, the free encyclopedia
Chebyshev's theorem is a name given to several theorems proven by Russian mathematician Pafnuty Chebyshev
- Bertrand's postulate
- Chebyshev's inequality
- Chebyshev's sum inequality
- The statement that if the function has a limit at infinity, then the limit is 1 (where π is the prime-counting function). This result has been superseded by the prime number theorem.
