This paper develops a non-local theory of liquid helium by building on an existing theory of healing for this material. It seeks to extend the validity of the macroscopic theories for He II near the ?-point by properly taking into account the fluctuations that dominate a second-order phase transition. To illustrate that the theory contains at least some of the correct physical ingredients, three situations are discussed-flow of a persistent supercurrent, propagation of small disturbances and healing at an infinite plane wall. © 1987 Oxford University Press.
