摘要: The correct quantum description for a curvature squared term in the action can be obtained by casting canonical form with introduction of variable which is negative first derivative field appearing action, only after removing total terms from action. We present Wheeler-DeWitt equation and obtain expression probability density current continuity. Furthermore, weak energy limit we classical Einstein equation. Finally solution wave
