The state of thermodynamic equilibrium of a one-dimensional Bose gas at nonzero temperature is considered. A method of calculating the correlation functions in this system is illustrated by the simplest example of the current correlation function. The expressions of the algebraic Bethe ansatz [1] are extremely helpful.
