Zusammenfassung:► We consider a superfluid p-wave Fermi gas with weak interaction at low temperatures. ► The weak interaction is described with Nozierese and Schmitt-Rink potential. ► We obtain the quasiparticle relaxation rate by using the Boltzmann equation approach. ► Then we calculate the components of shear viscosity and the diffusive thermal conductivity. In this paper, we obtain the shear viscosity and diffusive thermal conductivity of the superfluid p-wave Fermi gas with weak interaction by using the quasi-particle relaxation rate τP-1, and the Boltzmann equation approach at low temperatures. We show that τP-1 is proportional to T4. The shear viscosity components, ηxx, ηyy, ηxy are proportional to T−2, whereas ηxz, ηyz and ηzz are proportional to T−4 and T−6, respectively. The components of the diffusive thermal conductivity Kxx and Kyy are proportional to T−1, whereas Kzz is proportional to T−3.
