摘要：
The purpose of this paper is to discuss the evolution of modified holographic dark energy with variable G in non-flat Kaluza-Klein universe. We consider the non-interacting and interacting scenarios of the modified holographic dark energy with dark matter and obtain the equation of state parameter through logarithmic approach. It turns out that the universe remains in different dark energy eras for both cases. Further, we study the validity of the generalized second law of thermodynamics in this scenario. We also justify that the statefinder parameters satisfy the limit of Lambda CDM model.
