Description
This report is devoted to the study of temperature dependence of bulk
viscosity in SU(3)-gluodynamics. To calculate bulk viscosity we
measured the correlation function of the trace anomaly for a set of
temperatures in the region T/T_c \in (0.9, 1.5). We used multilevel
algorithm which allowed us to improve the accuracy of the data. To
extract the values of bulk viscosity we used two approaches: fitting
of the data by physically motivated ansatz and the Backus-Gilbert
method.
