Quantum cosmology with R + R 2 gravity

摘要: Canonical quantization of an action containing a curvature-squared term requires the introduction auxiliary variable. Boulware and coworkers prescribed technique to choose such variable, by taking derivative with respect highest field present in action. It has been shown that this can even be applied situations where variables is not required, leading wrong Wheeler–De Witt equation. also pointed out Boulware's prescription should taken up only after removing all possible total terms from Once done unique description quantum dynamics would emerge. For yields, for first time, mechanical probability interpretation cosmology, effective potential whose extremization leads Einstein's We conclude Einstein–Hilbert essentially modified by, at least, get formulation cosmology hence extend our previous work along scalar field.
