Abstract
We present cosmological models with variable cosmological term (Λ) in the context of higher-dimensional spacetime. It has been observed that in these models particle horizon exists and the cosmological term is decaying with time. Further, it is shown that the new models solve entropy problem and generate several models obtained in four-dimensional spacetime.
Keywords
