Joseph E. Lesnefsky, Damien A. Easson and Paul Davies constructed an uncountable infinite class of classical solutions which have H a v ≥ ≥ 0 and are geodesically complete. The authors claim that the geodesic incompleteness of inflationary spacetime is still an open issue. Furthermore, there are examples of infinite cyclic models solving the problem of unbounded entropy growth which are geodesically complete. In both of these studies, the authors argue that the previous investigations often did not use mathematically precise formulations of the BGV theorem and thus reached incomplete conclusions.
