Using the Tsallis generalized entropy, holographic
hypothesis and also considering the Hubble horizon
as the IRcutoff, we build a holographic model for dark energy
and study its cosmological consequences in the Brans–Dicke
framework. At first, we focus on a non-interacting universe,
and thereinafter, we study the results of considering a signchangeable
interaction between the dark sectors of the cosmos.
Our investigations show that, compared with the flat
case, the power and freedom of the model in describing the
cosmic evolution is significantly increased in the presence
of the curvature. The stability analysis also indicates that,
independent of the universe curvature, both the interacting
and non-interacting cases are classically unstable. In fact,
both the classical stability criterion and an acceptable behavior
for the cosmos quantities, including the deceleration and
density parameters as well as the equation of state, are not
simultaneously obtainable
