چکیده

We consider a spatially homogeneous and anisotropic Bianchi type-I universe which is
filled by pressureless dark matter (DM) and Tsallis holographic dark energy (THDE).
We assume the two dark components of the universe are interacting with each other
throughout a sign-changeable mutual interaction term. Various infra-red (IR) cutoffs
are studied, and it is obtained that all models display classical instability by themselves
at the future (z →−1). Moreover, we find out that some models can cross the phantom
line. In order to have a more comprehensive study, the statefinder diagnostic and the
ωD − ω
D plane are also investigated showing that the model parameters significantly
affect the evolution trajectories in the r − s and ωD − ω
D planes.
