Solutions to the Wheeler-Dewitt Equation Inspired by the String Effective Action | | James E. Lidsey
; | | Date: |
16 Dec 1993 | | Journal: | Class.Quant.Grav. 11 (1994) 1211-1224 | | Subject: | gr-qc | | Abstract: | The Wheeler-DeWitt equation is derived from the bosonic sector of the heterotic string effective action assuming a toroidal compactification. The spatially closed, higher dimensional Friedmann-Robertson-Walker (FRW) cosmology is investigated and a suitable change of variables rewrites the equation in a canonical form. Real- and imaginary-phase exact solutions are found and a method of successive approximations is employed to find more general power series solutions. The quantum cosmology of the Bianchi IX universe is also investigated and a class of exact solutions is found. | | Source: | arXiv, gr-qc/9312026 | | Services: | Forum | Review | PDF | Favorites | |
