2+1-dimensional gravity coupled to a dust shell: quantization in terms of global phase space variables
Alexander Andrianov, Yasser Elmahalawy, Artem Starodubtsev
We perform canonical analysis of a model in which gravity is coupled to a spherically symmetric dust shell in 2+1 spacetime dimensions. The result is a reduced action depending on…

Integrable Minisuperspace Models with Liouville Field: Energy Density Self-Adjointness and Semiclassical Wave Packets
Alexander A. Andrianov, Chen Lan, Oleg O. Novikov +1
The homogeneous cosmological models with a Liouville scalar field are investigated in classical and quantum context of Wheeler-DeWitt geometrodynamics. In the quantum case of quint…
