Midisuperspace-Induced Corrections to the Wheeler De Witt Equation
arXiv:hep-th/9203072 · doi:10.1103/PhysRevD.46.4758
Abstract
We consider the midisuperspace of four dimensional spherically symmetric metrics and the Kantowski-Sachs minisuperspace contained in it. We discuss the quantization of the midisuperspace using the fact that the dimensionally reduced Einstein Hilbert action becomes a scalar-tensor theory of gravity in two dimensions. We show that the covariant regularization procedure in the midisuperspace induces modifications into the minisuperspace Wheeler DeWitt equation.
