r""" List of the imaginary parts of the first 2,001,052 zeros of the Riemann zeta function, accurate to within 4e-9.
In order to use ``zeta_zeros()``, you will need to install the optional Odlyzko database package::
sage -i database_odlyzko_zeta
You can see a list of all available optional packages with ``sage --optional``.

EXAMPLES:
The following example prints the imaginary part of the 13th nontrivial zero of the Riemann zeta function::
sage: zz = zeta_zeros() # optional - database_odlyzko_zeta sage: zz[12] # optional - database_odlyzko_zeta 59.347044003 sage: len(zz) # optional - database_odlyzko_zeta 2001052 """ sobj = os.path.join(SAGE_SHARE, 'odlyzko', 'zeros.sobj') verbose("Loading Odlyzko database from " + sobj) return load(sobj) |
