Lindelöf's conjecture
The lindelöf conjecture is a conjecture made by Ernst Leonard Lindelöf in 1905 and is still unproven today about the order of the Riemann zeta function along the “critical straight line” .
The Lindelöfsche conjecture says that for and for everyone . There is also the Bachmann Landau symbol .
So far only weaker statements of the form could be proven: The value determined by Johannes van der Corput and Jurjen Koksma in 1930 has been gradually improved since then, most recently by Martin Huxley .
The Lindelöf hypothesis is weaker than the Riemann hypothesis : With a proof of the Riemann hypothesis the Lindelöf hypothesis would also be proven, but not the other way around.
