Abstract
A homogeneous cosmological model in higher dimension is obtained assum ing a time-dependent equation of state. It is observed that as usual 3 -D space expands, extra space (space belonging to the other dimensions ) reduces with time, thus exhibiting the desired feature of dimensiona l reduction. The dynamical behavior of the model is examined and it is noted that with a decrease in extra space the observable 3-D space en tropy increase, thus accounting for the large value of entropy observa ble at present.
