Minisuperspace Quantisation via Conditional Symmetries
We review the canonical quantisation of minisuperspace models by promoting to operators the constraints as well as the additional symmetries of the metric of the configuration space of variables. We describe the classical and quantum formulation of the theory and give an application of this approach to the FLRW spacetime coupled to a massless scalar field.
