Established a sufficient condition for geodesic completeness
Simplified the implementation of completeness criteria
Abstract
In this talk the possibility of constructing geodesically complete inhomogeneous stiff fluid cosmologies is discussed. A family with infinite parameters is derived. A wide and easy to implement sufficient condition for geodesic completeness is shown.
