摘要: Abstract We study a cosmological implication of holographic dark energy in the Brans–Dicke gravity. employ model to obtain equation state for density non-flat (closed) universe enclosed by event horizon measured from sphere named L. Our analysis shows that one can phantom crossing scenario if parameter α (of order unity) is tuned accordingly. Moreover, this behavior achieved treating scalar field as Chameleon and taking non-minimal coupling with matter. Hence generate phantom-like cosmology framework.
