Abstract
Transport coefficients of superfluid dipolar Fermi gas are calculated by using the Boltzmann equation approach. The interaction between Bogoliubov-Bogoliubov quasiparticles in the collision integral is considered in binary process. The shear viscosities n xz ↑ = n yy ↑, n xy ↑ ; n xz ↑ ≈ n yz ↑ ; and n u ↑ are proportional to T -6 ; T -8 ; and T -10 , respectively. Also, we have found the elements of the diffusive thermal conductivities K xx ↑ = K yy ↑ with temperature dependency T -5 and K u ↑ which is proportional to T -7 and other components which are zero.
