Abstract
It is possible to approximate the Riemann zeta-function by meromorphic functions which satisfy the same functional equation and satisfy (respectively do not satisfy) the analogue of the Riemann hypothesis.
In the other direction, it is possible to approximate meromorphic functions by various manipulations of the Riemann zeta-function.
