Phys. Rev. D 46, 4758–4760 (1992)Midisuperspace-induced corrections to the Wheeler-DeWitt equationReceived 26 May 1992; published in the issue dated 15 November 1992 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. The results apply to any scalar-tensor theory of gravity in two dimensions. © 1992 The American Physical Society URL:
