Barrow HDE model for Statefinder diagnostic in non-flat FRW universe

Understand

In this work we study a non-flat Friedmann-Robertson-Walker universe filled with a pressure-less dark matter (DM) and Barrow holographic dark energy (BHDE) whose IR cutoff is the apparent horizon.

• Among various DE models, (BHDE) model shows the dynamical enthusiasm to discuss the universe's transition phase.
• According to the new research, the universe transitioned smoothly from a decelerated to an accelerated period of expansion in the recent past.
• We exhibit that the development of $q$ relies upon the type of spatial curvature.
