Abstract
Some relationships of the nonlocal field operators developed by Siegert et al. and the usual free‐field operators are obtained. The interaction Hamiltonian derived with the help of these relationships is compared with the pseudopotential recently obtained by Liu and Wong. A study of the fluid dynamical equations at extreme low temperature has been made.Keywords
