Abstract
We discuss the possibility of observing superfluid phenomena in a quasi-one -dimensional weakly interacting Bose gas at finite temperature. The weaknes s of interaction in combination with generic properties of one-dimensional liquids can result in a situation where the relaxation time of the supercur rent flow is much longer than the system lifetime, and the behavior of the system is indistinguishable from that of a genuine superfluid.
