Summary
It is shown how to obtain Landau's equations for a superfluid in a symmetric conservative form. On account of the constraints involved, this case is more complicated than those of the classical theory developed by Godunov and by other authors.
Sunto
Si dimostra che è possibile porre in forma simmetrica conservativa il sistema di equazioni di Landau del superfluido. A causa dei vincoli a cui é soggetto il moto del sistema la teoria che si usa risulta piú complessa di quella classica sviluppata da Godunov e da altri autori.
