We derive cosmological constraints using a galaxy cluster sample selected
from the 2500 deg$^2$ SPT-SZ survey. The sample spans the redshift range
$0.255$. The sample is supplemented with optical weak
gravitational lensing measurements of 32 clusters in the range $0.29

We derive cosmological constraints using a galaxy cluster sample selected
from the 2500 deg$^2$ SPT-SZ survey. The sample spans the redshift range
$0.25<z<1.75$ and consists of 377 cluster candidates with SZ detection
significance $xi>5$. The sample is supplemented with optical weak
gravitational lensing measurements of 32 clusters in the range $0.29<z<1.13$
(using data from Magellan and the Hubble Space Telescope) and X-ray
measurements of 89 cluster in the range $0.25<z<1.75$ (from Chandra). We rely
on minimal modeling assumptions: i) weak lensing provides an accurate means of
measuring halo masses, ii) the mean SZ and X-ray observables are related to the
true halo mass through power-law relations in mass and dimensionless Hubble
parameter $E(z)$ with a-priori unknown parameters, iii) there is (correlated,
lognormal) intrinsic scatter and scatter due to measurement uncertainties
relating these observables to their mean relations. Assuming a flat
$nuLambda$CDM model, in which the sum of neutrino masses is a free parameter,
we measure $Omega_mathrm{m}=0.276pm0.047$, $sigma_8=0.781pm0.037$, and the
parameter combination $sigma_8(Omega_mathrm{m}/0.3)^{0.2}=0.766pm0.025$.
The redshift evolution of the X-ray $Y_X$–mass and $M_mathrm{gas}$–mass
relations are both consistent with self-similar evolution to within $1sigma$.
The mass-slope of the $Y_X$–mass relation shows a $2.3sigma$ deviation from
self-similarity. The mass-slope of the $M_mathrm{gas}$–mass relation is
steeper than self-similarity at the $2.5sigma$ level. In a $nu w$CDM
cosmology, we measure the dark energy equation of state parameter
$w=-1.55pm0.41$ from the cluster data. We perform a measurement of the growth
of structure since redshift $zsim1.7$ and find no evidence for tension with
the prediction from General Relativity. (abridged)
