The graceful exit problem

WebIn physical cosmology, the graceful exit problem refers to an inherent flaw in the initial proposal of the inflationary universe theory proposed by Alan Guth in 1981. In Guth’s model, the period of accelerated expansion (a.k.a. inflation) makes the universe homogeneous … Web30 Apr 2024 · SIGTERM is a Linux signal that Unix-based operating systems issue when they want to terminate a running process. In normal circumstances, your application should respond to a SIGTERM by running cleanup procedures that facilitate graceful termination. If processes aren’t ready to terminate, they may elect to ignore or block the signal.

The curvature and the dilaton energy stay finite at all times, in both the string and Einstein frames. In the string frame, the dilaton tends to a constant value at late times after the bounce. I.
