✦ Synopsis

Dispersion relations for hydrodynamic modes are normally derived in the limit of small damping. This limit covers the entire hydrodynamic region as long as the region conincides with the small damping region (e.g., in 4He-II). This is not the case in superfluid 3He.

In this paper the dispersion relations of second sound and sq-mode are generalized throughout the hydrodynamic region.

It might have experimental implications for any 3He experiment dealing with frequencies of Hz and higher.

They are discussed in detail.

Using the path integration technique, developed by Brusov and Popov earlier for investigation of collective properties of superfluid phases of He 3 we study the collective mode spectrum in polar phase of He 3. This phase has points and lines of gap nodes. We derived equations, describing all 18 coll
