The quasiclassical, Eilenberger-type equations are applied to description of rotating P-wave pyroelectric-type superconductor in the presence of magnetic field H and superflow υ. In analogy to type-II superconductors the possibility of vortex solution is discussed. We determine the symmetry of eigensolutions and the upper critical velocity Ω_{c2}. We discuss the paramagnetic critical behaviour of the system depending on the strength of spin-orbit interaction.
The superfluid ^{3}He is considered in confined geometry for arbitrary thickness when surface roughness is taken into account. The equilibrium states, the critical size when the two-dimensional state is realized exclusively, and the critical thickness below which superfluidity is destroyed are defined, found and discussed with reference to the essential parameters of a system. Some particular cases are examined analytically. The examples of exact numerical solutions are presented.
