A Closed Universe with Maximum Life-Time

arXiv:1905.11525

Abstract

A closed universe with maximum life-time is constructed using optimal control. Einstein's field equations are used with varying cosmological "constant". The second time derivative of the Hubble parameter acts as the control function in the optimal control model.
